what is xylene used for

The three isomeric xylenes each have a molecular formula of C 8 H 10, though the more informative semi-structural formula C 6 H 4 (CH 3) 2 is also used commonly. The chemical formula for xylene is C8H10, or more specifically (C6H4)(CH3)2. Xylene (from Greek ξύλο, xylo, "wood"), xylol or dimethylbenzene is any one of three isomers of dimethylbenzene, or a combination thereof. With the formula (CH3)2C6H4 Solvent applications and industrial purposes Xylene is used as a solvent. A mixture of xylene isomers used as a solvent in making lacquers and rubber cement and as an aviation fuel.

Alcohol, however, is not miscible with paraffin (something that is miscible can mix well with another substance). In terms of volume, xylene is one of the top 30 chemicals produced in the United States. Fixed tissue is then dehydrated, removing water from the tissue by escalating grades of alcohol. [6], Xylenes form azeotropes with water and a variety of alcohols. [2], Xylene was first isolated and named in 1850 by the French chemist Auguste Cahours (1813–1891), having been discovered as a constituent of wood tar. Once the sections are prepared, they are usually stained, to help distinguish the components of the tissue. Xylene, xylol or dimethylbenzene is any one of three isomers of dimethylbenzene, or a combination thereof. Xylene in air can be smelled at concentrations as low as 0.08 to 3.7 ppm (parts of xylene per million parts of air) and can be tasted in water at 0.53 to 1.8 ppm. The least valued of the isomers is meta -xylene, but it has uses in the manufacture of coatings and plastics. The isomers can be distinguished by the designations ortho- (o-), meta- (m-) and para- (p-), which specify to which carbon atoms (of the benzene ring) the two methyl groups are attached. The mixture is referred to as both xylene and, more precisely, xylenes. It is crucial to wear safety goggles when working with xylene. This aids histopathology technicians who look at tissues to determine the presence of disease. Klean-Strip® Xylene . [26][27] The presence of methylhippuric acid can be used as a biomarker to determine exposure to xylene. For instance chlorination of both methyl groups gives the corresponding xylene dichlorides (bis(chloromethyl)benzenes) whilst mono-bromination yields xylyl bromide, a tear gas agent used in World War I. Xylene is flammable but of modest acute toxicity, with LD50 ranges from 200 to 5000 mg/kg for animals. However, toluene is considered as a toxic compound. For more information go to www.P65Warnings.ca.gov. [7][12] o-Xylene is an important precursor to phthalic anhydride. What is Xylene Used for? The mixture is referred to as both xylene and, more precisely, xylenes. The major use of meta -xylene is in the production of isophthalic acid, which is used as a copolymerizing monomer to alter the properties of polyethylene terephthalate. The principal mechanism of detoxification is oxidation to methylbenzoic acid and hydroxylation to hydroxylene. uses In chemical industry: Xylene Ortho -xylene is used mostly to produce phthalic anhydride, an important intermediate that leads principally to various coatings and plastics. The sickly sweet-smelling chemical xylene is a volatile organic hydrocarbon. Since one of the paraxylene uses includes the synthesis of PTA, it also serves to make other compounds such as cyclohexanedimethanol, terephthaloyl chloride and various other polymers. Of the three isomers, the p-isomer is the most industrially sought after since it can be oxidized to terephthalic acid. If xylene comes in contact with the eyes, it can damage the cornea. Xylene is used as a feedstock in the production of petrol. [13] In thinning paints and varnishes, it can be substituted for toluene where slower drying is desired, and thus is used by conservators of art objects in solubility testing. In tissue processing, tissue has to be embedded in a medium (such as paraffin) to support it and allow it to be cut without damaging the tissue. [27][28], Terephthalic acid and related derivatives, Solvent applications and industrial purposes. Toluene is a good solvent that is commonly used in the production of paints. What Personal Protective Equipment (PPE) is needed when working with xylene? In thinning paints and varnishes, it can be substituted for toluene where slower drying is desired. The PET in turn is a chief ingredient in various plastic fibers and films. It is a good cleaning agent for silicon wafers, steel and to sterilize many substances. Acute (short- A xylene (from Greek ξυλος, xylos, "wood") is an aromatic hydrocarbon consisting of a benzene ring with two methyl substituents. Always review material safety data sheets in areas that use xylene and other powerful chemicals. Xylene is a colorless mixture of chemically-related hydrocarbons that often finds use as a solvent for paints and printing inks. Xylene’s powerful solvent properties are used in printing, rubber and leather processing. It is widely used in several industries as well as in dental and medical arenas. Xylene, also called xylol, dimethyl benzene, Violet 3, and methyl toluene, is an isomer that can be found in three forms. And when preparing slides for microscopy, xylene can remove any remaining wax from slides. With the formula (CH3)2C6H4, each of the three compounds has a central benzene ring with two methyl groups attached at substituents. There are many uses of xylene, both in its pure state and in compounds. The melting point ranges from −47.87 Â°C (−54.17 Â°F) (m-xylene) to 13.26 Â°C (55.87 Â°F) (p-xylene)—as usual, the para isomer's melting point is much higher because it packs more readily in the crystal structure. In drilling mud testing, a 50/50 xylene/ isopropanol (IPA) mixture had been used to break oil-mud emulsions prior to titrations to measure alkalinity , chloride and calcium. There are not many broad uses for p-xylene-2-sulfonic acid. [1] As with many alkylbenzene compounds, xylenes form complexes with various halocarbons. For light microscopy, three techniques can be used: the paraffin technique, frozen sections, and semithin sections. See more. Xylene… Like the individual isomers, the mixture is colorless, sweet-smelling, and highly flammable. Xylene is a colorless liquid and vapor. These three chemicals are then used to make PET. Most sports cars or racing cars need 92 octane gas rather than just the standard 87 level of octane most cars take. [17] Xylene is used to remove paraffin from dried microscope slides prior to staining. Not intended for sale or use in California. Xylenes are released into the atmosphere as fugitive emissions from industrial sources, from auto exhaust, and through volatilization from their use as solvents. Children are more greatly affected by xylene than adults, so extraordinary care must be taken to prevent their exposure. Toluene is mainly used as a precursor to benzene via hydrodealkylation: C 6 H 5 CH 3 + H 2 → C 6 H 6 + CH 4. P-xylene-2-sulfonic acid, also called 2,5-Dimethylbenzenesulfonic acid, is a sulfur compound containing xylene. It is manufactured as a white crystalline powder. As nouns the difference between toluene and xylene is that toluene is (organic compound) a colourless, inflammable liquid hydrocarbon, methylbenzene, ch 3 c 6 h 5, used as a solvent, in high-octane fuels and in the production of many chemical compounds while xylene is (chemistry) any of a group of three isomeric aromatic hydrocarbons, di-methyl-benzene, found in coal and wood tar. Areas of application include the printing, rubber, and leather industries. Any ingestion by mouth should be taken very seriously as well by quickly obtaining medical aid. The chemical and physical properties of xylene differ according to the respective isomers. Xylene is a liquid, and it can leak into soil, surface water (creeks, streams, rivers), or groundwater. [20][clarification needed] A condition called chronic solvent-induced encephalopathy, commonly known as "organic solvent syndrome" has been associated with xylene exposure. Xylene is used in some glue. Xylene is a volatile organic hydrocarbon used across many industries including medicine, dentistry and plastics. Xylene. At an exposure of 100 ppm, one may experience nausea or a headache. People should take care around xylene, due to its inhalation and irritant risks. Chemical formula: C8H10. Published 1 July 2014 Last updated 31 January 2019 — see all updates. Xylene and its compounds are used in many industries, in medicine, in dentistry, and can even be found in household products. Xylene is used in many industries. With water the azeotrope consists of 60% xylenes and boils at 94.5 Â°C. At an exposure between 200 and 500 ppm, symptoms can include feeling "high", dizziness, weakness, irritability, vomiting, and slowed reaction time. The primary risks of xylene exposure include effects from inhalation or contact with the skin or eyes. Xylene is primarily used as a solvent (a liquid that can dissolve other substances), particularly in the printing, rubber and leather industries. 2. The boiling point for each isomer is around 140 Â°C (284 Â°F). Therefore it is wise to remove persons from low-lying areas near the xylene contamination. This can lead to drying and cracking of the skin and dermatitis. One of the chief paraxylene uses is in polymer synthesis. Xylene is considered a central nervous system depressant, meaning it slows down the central nervous system. This makes paraxylene absolutely essential in the production of polyethylene terephthalate, or PET. It Is a Powerful Solvent. There are three main isomers of xylene, called ortho-xylene, meta-xylene and paraxylene. The level of exposure depends upon the dose, duration, and work being done. Oral LD50 for rats is 4300 mg/kg. [3], Xylene exists in three isomeric forms. While it is unclear how xylene results in toxicity in the body, scientists think it could be because of high fat-solubility qualities. Xylidine definition, any of six isomeric compounds that have the formula C8H11N, are derivatives of xylene, and resemble aniline: used in dye manufacture. Several million tons are produced annually. In histology, xylene is used to process and stain tissues. While there are proposed alternatives to xylene in tissue processing, it is still considered the best chemical for tissue processing and staining purposes. Long-term exposure may lead to headaches, irritability, depression, insomnia, agitation, extreme tiredness, tremors, hearing loss, impaired concentration and short-term memory loss. For similar reasons, it is often the active ingredient in commercial products for ear wax (cerumen) removal.(1). Paraxylene is one of the three isomers of xylene. The use of impervious gloves and masks, along with respirators where appropriate, is recommended to avoid occupational health issues from xylene exposure. Increased xylene additives are added to gasoline to increase the octane level. b) Also compute the air required if the operation is carried out in Qm= For example, when painting with lacquer, the wash of choice would be lacquer thinner. Xylene is not classified as a carcinogen. It can be made by crystallization and adsorption. Xylenes are produced mainly as part of the BTX aromatics (benzene, toluene, and xylenes) extracted from the product of catalytic reforming known as reformate. [1], Xylenes are produced by the methylation of toluene and benzene. It is used as a solvent and emulsion breaker in workover operations to clean up reservoirs. Additional uses of xylene include its addition to pesticides and disinfectants. [14] Similarly it is a cleaning agent, e.g., for steel, silicon wafers, and integrated circuits. The skin quickly absorbs it. It is flammable at room temperature. In dentistry, xylene can be used to dissolve gutta percha, a material used for endodontics (root canal treatments). Although conversion to terephthalic acid is the dominant chemical conversion, xylenes are precursors to other chemical compounds. It is used as a solvent, in jet fuel, and in the manufacture of dyes, fibers, perfumes, and films. Visual impairment and difficulty may also result from xylene exposure. [18], Hearing disorders have been also linked to xylene exposure, both from studies with experimental animals,[21][22] as well as clinical studies. High-octane gas costs more as it increases the power in your engine. [1] In 2011, a global consortium began construction of one of the world's largest xylene plants in Singapore. WARNING: This product can expose you to chemicals including Ethylbenzene and Cumene, which are known to the State of California to cause cancer. p-Xylene is the principal precursor to terephthalic acid and dimethyl terephthalate, both monomers used in the production of polyethylene terephthalate (PET) plastic bottles and polyester clothing. Xylene is primarily used as a solvent (a liquid that can dissolve other substances), particularly in the printing, rubber and leather industries. Other drastic symptoms might include tremors, heart arrhythmias and pulmonary edema. Xylene is an organic compound having the chemical formula (CH 3) 2 C 6 H 4. Information on xylene, for use in responding to chemical incidents. [18], Xylenes are metabolized to methylhippuric acids. Xylene is used as a solvent. Similarly it is a cleaning agent for … The reason xylene works so well for tissue processing is that it makes tissues transparent so that paraffin can fully envelop the tissue. Xylene is also used as a cleaner. Dianne features science as well as writing topics on her website, jdiannedotson.com. xylol or dimethylbenzene is any one of three isomers of dimethylbenzene, or a combination thereof. Copyright 2020 Leaf Group Ltd. / Leaf Group Media, All Rights Reserved. Xylene can be applied in three ways, all of which depend on the antiquing and/or cleaning method used when the concrete was stamped. [10] The complexes of different isomers often have dramatically different properties from each other.[11]. What is Xylene? Paraxylene, also called p-xylene, is a chemical essential to the process of manufacturing PET plastic bottles, x-ray film and polyester fiber. It is a common component of ink, rubber, and adhesives.

Xylene is not soluble in water and will float on top of denser water if combined. The xylene mixture is a slightly greasy, colorless liquid commonly encountered as a solvent. They are all colorless, flammable liquids, some of which are of great industrial value. They are all colorless, flammable liquids, some of which are of great industrial value. The great attraction of PET is its versatility, its relative affordability, lack of shattering and its ability to be recycled. Xylene is used in the production of terephthalic acid monomer. In this case it is used as clearing agent. [1][4] Commercial or laboratory-grade xylene produced usually contains about 40-65% of m-xylene and up to 20% each of o-xylene, p-xylene and ethylbenzene. These conversions are catalyzed by zeolites.[1]. This helps with slide staining so that features of the tissue are more easily viewed under a microscope. It was named after xylong, the Greek word for wood, because it was found in crude wood spirit. Xylene also poses risks to skin and eyes and is considered a skin irritant. Workers may be harmed from exposure to xylene. Xylene is used in some glue. ZSM-5 is used to facilitate some isomerization reactions leading to mass production of modern plastics. Learn more. If you are still wondering about what is xylene used for in painting, then … Xylene is found in small amounts in airplane fuel and gasoline. It is primarily used as a solvent to remove paint, oil, grease, marker, and ink. Xylene occurs A fourth isomer is ethylbenzene. Meta-xylene is a main component of commercial-grade xylene. 98% of p-xylene production, and half of all xylenes produced is consumed in this manner. Even smelling it can affect major organs. Paraxylene is used to make terephthalic acid, or TPA; purified terephthalic acid, or PTA; and dimethyl-terephthalate, or DMT. After staining, microscope slides are put in xylene prior to mounting with a coverslip. It may seem odd, but solvents are chemical composites that are similar on … By counting the carbon atoms around the ring starting from one of the ring carbons bonded to a methyl group, and counting towards the second methyl group, the o-isomer has the IUPAC name of 1,2-dimethylbenzene, the m-isomer is 1,3-dimethylbenzene and the p-isomer is 1,4-dimethylbenzene. Solvent xylene often contains a small percentage of ethylbenzene. Xylene is also used as a cleaner. The paraffin technique is the most commonly used. J. Dianne Dotson is a science writer with a degree in zoology/ecology and evolutionary biology. For large scale use of this product: use non-sparking ventilation systems, approved explosion-proof equipment and intrinsically safe electrical systems in areas where this product is used and stored. Xylene is an excellent solvent, especially for aromatic solids such as asphaltic materials. Longer exposure to xylene yields greater risk. Thins Paints & Lacquers. Commercial or mixed xylene usually contains about 40-65% m-xylene and up to 20% each of o-xylene and p-xylene and ethylbenzene. In the petroleum industry, xylene is also a frequent component of paraffin solvents, used when the tubing becomes clogged with paraffin wax. As it happens, xylene is highly miscible with paraffin. Precursor to benzene and xylene. Xylene is used as a solvent for printing, rubber, and leather industries. The best protective measures you can take around xylene are to work in a properly ventilated environment, such as a hood that vents quickly outside the area; a respirator mask as needed; and to wear proper protective eye goggles, gloves, protective clothes and aprons. In this way it could be soluble with lipids in the membranes of neurons, and could affect neuronal proteins as a result. While xylene serves many valuable uses across multiple industries, it comes with its own risks to those who work closely with this chemical compound. The nauseatingly sweet smell of xylene serves as a warning for its toxic nature. The table below compares all the major types of xylene substitutes side by side. Exposed individuals should be removed from the contamination, and medical assistance should be sought. It’s used in the petroleum and wood processing industries. Xylene can react with strong acids and oxidizers. Paraxylene uses include precursor raw material for other substances. Xylenes are an important petrochemical produced by catalytic reforming and also by coal carbonisation in the manufacture of coke fuel. Nitration of toluene give mono-, di-, and trinitrotoluene, all of which are widely used. Nitration. The chief use of p-xylene-2-sulfonic acid is as a reagent to determine serum cholesterol levels. Xylene, any of three isomeric dimethylbenzenes [which have the same chemical formula, C 6 H 4 (CH 3) 2, but different molecular structure], used as solvents, as components of aviation fuel, and as raw materials for the manufacture of dyes, fibres, and films. Xylene’s structure consists of two methyl groups attached to a six-carbon ring. Xylene consists of a benzene ring with two methyl (CH3) groups attached, and occurs in three isomeric forms. Other synonyms for xylene are dimethyl benzene, methyl toluene, xylol and mixed xylenes. It is listed as a sulfonic acid and is considered a biochemical. Xylene is used as a solvent and in the printing, rubber, and leather industries. It is a common component of ink, rubber, and adhesive. Xylene can also cause headaches, dizziness, confusion, loss of muscle coordination, and in high doses, death. Because xylene is so efficient at removing fats, any contact with the skin will have the same effect. From: Public Health England. [23][24][25], Xylene is also a skin irritant and strips the skin of its oils, making it more permeable to other chemicals. The second ranked application involves its disproportionation to a mixture of benzene and xylene. Breathing in xylene can cause dizziness, nausea, fainting, headache and even vomiting. Any of three colorless flammable isomeric benzene derivatives, C8H10, obtained from wood and coal tar. The density of each isomer is around 0.87 g/mL (7.26 lb/U.S. Isomers of xylene are used in the manufacture of certain polymers (chemical compounds), such as plastics. It is a volatile liquid giving off its gas. lol n. 1. One of the chief uses of xylene is as a lubricant, and it is so used in motor oil or brake fluid. Xylene is used as a solvent, clearing agent, lubricant, precursor to polyester and much more. Because xylene is heavier than air, it can reside in pockets near the ground. Since it naturally occurs in petroleum, it is not surprising that it is also found in gasoline and jet fuel. She spent nine years working in laboratory and clinical research. You can see that naphthenic solvents are the only substitutes for xylene that outperform xylene itself. p -Xylene is used as a feedstock in the production of terephthalic acid, which is a monomer used in the production ofpolymers. Xylene is also used as: - Cleaning Agent - Paint Thinner and Remover - Varnish - Airplane Fuel - Gasoline - Shellac - Rust Preventatives - Pesticides - Lacquers. Figures in the table less than 1.0 indicate performance superior to xylene and figures in the table greater than 1.0 indicate performance inferior to xylene. [5][6][7] The ratio of isomers can be shifted to favor the highly valued p-xylene via the patented UOP-Isomar process[8] or by transalkylation of xylene with itself or trimethylbenzene. Most xylene that is accidentally released evaporates into the air, although some is released into rivers or lakes. With the formula (CH3)2C6H4, each of the three compounds has a central benzene ring with two methyl groups attached at substituents. If the excess antiquing release was thoroughly removed before the original seal coat was applied * , the best way to fix sealer problems is to fill a pail with xylene, and use a natural-bristle brush (on a broom handle) to scrub the xylene onto the surface. The demand for isophthalic acid is relatively modest so m-xylene is rarely sought (and hence the utility of its conversion to the o- and p-isomers). More research is needed to determine the method of toxicity. It is traditionally used in the leather, rubber, and paint industries, particularly as a solvent, a cleaning agent, and a paint thinner. Xylene is a component of lubricants in motor oil, paints and paint thinners, polishes, waxes, antifreeze, sealants, adhesives, and even gasoline and cigarettes. Also, any xylene vapor trapped in clothing can affect helpers. Documents. In this application, with a mixture of isomers, it is often referred to as xylenes or xylol. gallon or 8.72 lb/imp gallon) and thus is less dense than water. Xylene is used in the laboratory to make baths with dry ice to cool reaction vessels,[15] and as a solvent to remove synthetic immersion oil from the microscope objective in light microscopy. It is known for being a major component of plastic soda bottles, detergent bottles, bottles for various household cleaners and makeup. The continued versatility of paraxylene ensures its continued demand. Food packaging also may contain PET, and it also serves as a polyester fiber component for such things as clothing and household fabrics. Xylene is used, to a lesser extent, as a material in the chemical, plastics, and synthetic fiber industries and as an ingredient in the coating of fabrics and papers. Xylene can enter the environment when it is made, packaged, shipped, or used. These tissues can then be used in microscopy. It is used in orographic film and x-rays. Additional uses of xylene include its addition to pesticides and disinfectants. Paraxylene boasts a number of uses in the polymer industry. It is also found in small proportions in gasoline and jet fuel. [16] In histology, xylene is the most widely used clearing agent. Those who work regularly with xylene should be given routine medical examinations, and have body fluids monitored. It is sometimes used as a fuel due to its high flammability. However, prolonged exposure to xylene can be hazardous to the health of the user, and it is recommended to seek alternatives to avoid unsafe conditions. There is very little information available that isolates xylene from other solvent exposures in the examination of these effects. Xylene is heavier than air. Xylene is a petroleum-based synthetic chemical that is colorless, flammable, and produces a sweet odor. This smell can be detected in air concentrations as low as one part per million (PPM)! Xylene is one of the top chemicals produced in the U.S., and it is commonly derived from crude petroleum. You can add xylene yourself to increase the octane level in your gas. Small quantities occur in gasoline and aircraft fuels. They also occur in crude oil in concentrations of about 0.5–1%, depending on the source. A lifelong writer, Dianne is also a content manager and science fiction & fantasy novelist. [18][19], The side effects of exposure to low concentrations of xylene (< 200 ppm) are reversible and do not cause permanent damage. Xylene. P-xylene-2-sulfonic acid is soluble in ethanol. [1], The main effect of inhaling xylene vapor is depression of the central nervous system (CNS), with symptoms such as headache, dizziness, nausea and vomiting. Xylene is a component of lubricants in motor oil, paints and paint thinners, polishes, waxes, antifreeze, sealants, adhesives, and even gasoline and cigarettes.
