History
The compound was first isolated and kept in 1837 through a distillation of pine oil by Pierre Joseph Pelletier and Filip Neriusz Walter, who named it rétinnaphte.[19][20] In 1841, Henri Étienne Sainte-Claire Deville isolated a hydrocarbon from balsam of Tolu (an aromatic extract from the tropical Colombian tree Myroxylon balsamum), which Deville recognized as similar to Walter’s rétinnaphte and to benzene; hence he called the new hydrocarbon benzoène.[21][22][23] In 1843, Jöns Jacob Berzelius recommended the alternative name for it which was toluin.[24] In 1850, French chemist Auguste Cahours isolated from a distillate of wood a hydrocarbon which he recognized as similar to Deville’s benzoène and which Cahours named toluène.[25][26]
Chemical properties
The distance between carbon atoms in the toluene ring is 0.1399 nm. The C-CH3 bond is longer at 0.1524 nm, while the average C-H bond length is 0.111 nm.[27]
Ring reactions
Toluene reacts as a normal aromatic hydrocarbon in electrophilic aromatic substitution.[28][29][30] Because the methyl group has greater electron-releasing properties than a hydrogen atom in the same position, toluene is more reactive than benzene toward electrophiles. It undergoes sulfonation to give p-toluenesulfonic acid, and chlorination by Cl2 in the presence of FeCl3 to give ortho- and para- isomers of chlorotoluene.
Nitration of toluene gives mono-, di-, and trinitrotoluene, all of which are widely used. Dinitrotoluene is the precursor to toluene diisocyanate, a precursor to polyurethane foam. Trinitrotoluene (TNT) is an explosive.
Complete hydrogenation of toluene gives methylcyclohexane. The reaction requires a high pressure of hydrogen and a catalyst.
Side chain reactions
The C-H bonds of the methyl group in toluene are benzylic, therefore they are weaker than C-H bonds in simpler alkanes. Reflecting this weakness, the methyl group in toluene undergoes a variety of free radical reactions. For example, when heated with N-bromosuccinimide (NBS) in the presence of AIBN, toluene converts to benzyl bromide. The same conversion can be effected with elemental bromine in the presence of UV light or even sunlight.
Toluene may also be brominated by treating it with HBr and H2O2 in the presence of light.[31]
- C6H5CH3 + Br2 → C6H5CH2Br + HBr
Benzoic acid and benzaldehyde are produced commercially by partial oxidation of toluene with oxygen. Typical catalysts include cobalt or manganese naphthenates.[32] Related but laboratory-scale oxidations involve the use of potassium permanganate to yield benzoic acid and chromyl chloride to yield benzaldehyde (Étard reaction).
The methyl group in toluene undergoes deprotonation only with very strong bases; its pKa is estimated using acidity trends to be approximately 43 in dimethyl sulfoxide (DMSO)[33][34] and its ion pair acidity is extrapolated to be 41.2 in cyclohexylamine (Cesium Cyclohexylamide) using a Bronsted correlation.[35][36]
Miscibility
Toluene is miscible (soluble in all proportions) with ethanol, benzene, diethyl ether, acetone, chloroform, glacial acetic acid and carbon disulfide, but immiscible with water.[37]
Production
Toluene occurs naturally at low levels in crude oil and is a byproduct in the production of gasoline by a catalytic reformer or ethylene cracker. It is also a byproduct of the production of coke from coal. Final separation and purification is done by any of the distillation or solvent extraction processes used for BTX aromatics (benzene, toluene, and xylene isomers).[15]
Other preparative routes
Toluene can be prepared by a variety of methods. For example, benzene reacts with methanol in presence of a solid acid to give toluene and water:[15]
- C6H6+CH3OH→toC6H5CH3+H2O

Uses
Toluene is one of the most abundantly produced chemicals. Its main uses are (1) as a precursor to benzene and xylenes, (2) as a solvent for thinners, paints, lacquers, adhesives, and (3) as an additive for gasoline.[15] In 2013, worldwide sales of toluene amounted to about 24.5 billion US dollars.[38]
Precursor to benzene and xylenes
Toluene is converted to benzene via hydrodealkylation:
- C6H5CH3 + H2 → C6H6 + CH4
Its transalkylation gives a mixture of benzene and xylenes.
Solvent
Toluene is widely used in the paint, dye, rubber, chemical, glue, printing, and pharmaceutical industries as a solvent.[39] Nail polish, paintbrush cleaners, and stain removers may contain toluene. Manufacturing of explosives (TNT) uses it as well. Toluene is also found in cigarette smoke and car exhaust. If not in contact with air, toluene can remain unchanged in soil or water for a long time.[40]
Toluene is a common solvent, e.g. for paints, paint thinners, strippers, silicone sealants,[41] many chemical reactants, rubber, printing ink, adhesives (glues), lacquers, leather tanners, and disinfectants.[15]

Toluene Chemical Properties,Uses,Production
Description
Toluene is a clear, colourless liquid with a sweet, benzene-like odour. Toluene occurs naturally in crude oil and in the toluene tree. It is also produced in the process of making gasoline and other fuels from crude oil and making coke from coal. Toluene is used in making paints, paint thinners, fingernail polish, lacquers, adhesives, and rubber and in some printing and leather tanning processes. Toluene is also used in the production of polymers used to make nylon, plastic soda bottles, and polyurethanes and for pharmaceuticals, dyes, cosmetic nail products, and the synthesis of organic chemicals.
Toluene has been reported as the most commonly abused hydrocarbon solvent, primarily through ‘glue sniffing’. The common possibilities of exposure to high levels of toluene include indoor air from the use of household products such as paints, paint thinners, adhesives, synthetic fragrances, and many other sources.
Chemical Properties
Toluene is a clear, colorless, flammable liquid with a sweet/pungent odor. It is extensively used as a solvent in different industries, i.e., rubber chemical manufacturing, drugs and pharmaceuticals, thinner for inks, paints dyes, and perfume manufacturing. It is a natural constituent of crude oil and is produced from petroleum refi ning and coke-oven operations. Toluene occurs naturally as a component of crude oil and occurs in petroleum refi ning and coke oven operations. Occupational workers associated with several kinds of activities, such as manufacturing of dyes, printing inks, painting automobile mechanics, gasoline manufacturers, shippers, and retailers, adhesives and coatings manufacturers and applicators, audio-equipment product workers, chemical industry workers, coke-oven workers, fabric manufacturers (fabric coating), sites of hazardous wastes, linoleum manufacturers, in pharmaceutical manufacturing, printing works, shoe manufacturing industry, become exposed to toluene.
Physical properties
Colorless, clear, flammable liquid with a pleasant, sweet or paint-like odor similar to benzene. At 40 °C, the lowest concentration at which an odor was detected were 960 μg/L. Similarly at 25 °C, the lowest concentration at which a taste was detected was 960 μg/L (Young et al., 1996). Experimentally determined detection and recognition odor threshold concentrations were 600 μg/m3 (160 ppbv) and 7.0 mg/m3 (1.9 ppmv), respectively (Hellman and Small, 1974). Leonardos et al. (1969) reported higher odor threshold concentrations for toluene derived from coke (4.68 ppmv) and petroleum (2.14 ppmv). The average least detectable odor threshold concentrations in water at 60 °C and in air at 40 °C were 24 and 140 μg/L, respectively (Alexander et al., 1982). An odor threshold concentration of 330 ppbv was determined by a triangular odor bag method (Nagata and Takeuchi, 1990). Cometto-Muiz and Cain (1994) reported an average nasal pungency threshold concentration of 29,574 ppmv.
History
Toluene is a clear, flammable, aromatic hydrocarbon liquid with a smell similar to benzene. It is also called methylbenzene, indicating that a methyl group has been added to one of benzene’s carbon atoms. Toluene was first isolated by Pierre-Joseph Pelletier (1788–1842) and Philippe Walter (1810–1847) in 1837. The name toluene comes from the South American tree Toluifera balsamum. Henri-Etienne Sainte-Claire Deville (1818–1881) isolated toluene from the tree’s gum, Tolu balsam, in 1841.
The main source of toluene is from the catalytic reforming of naphthas during petroleum processing. During this process cycloalkanes are dehydrated, forming aromatics such as toluene and xylene along with hydrogen. Toluene can also be obtained from the pyrolysis of gasoline. It is a by-product when styrene is produced and can also be produced from coal tar, which was its main source in the first half of the 20th century.
Uses
Toluene is derived from coal tar as well aspetroleum. It occurs in gasoline and manypetroleum solvents. Toluene is used to producetrinitrotoluene (TNT), toluene diisocyanate,and benzene; as an ingredient fordyes, drugs, and detergents; and as an industrialsolvent for rubbers, paints, coatings, andoils.
Preparation
Toluene is the starting material for the production of tolylene diisocyanate (TDI)，the process may be varied to give products of differing isomer contents. The nitration of toluene (with a nitrating mixture containing 20% nitric acid, 60% sulphuric acid and 20% water at 30-45°C) gives a mixture of 2-nitrotoluene (about 60%) and 4- nitrotoluene (40%). If this mixture is nitrated further (with a mixture of 35% nitric acid and 65% sulphuric acid at 65-80°C) without separation, the product is a mixture of2,4-dinitrotoluene (about 80%) and 2,6-dinitrotoluene (20%). If, on the other hand, the mixed mononitrates are separated (by distillation), then further nitration of the 2-nitrotoluene yields a mixture of 2,4-dinitrotoluene (about 65%) and 2,6-dinitrotoluene (35%) whilst further nitration of the 4-nitrotoluene gives only 2,4-dinitrotoluene.
Production Methods
Benzene is produced from toluene through a process called hydrodealkylation. In thisprocess, toluene reacts with hydrogen in the presence of a chromium, platinum, or molybdenumcatalysts at temperatures of several hundred degrees Celsius and pressures of about50 atmospheres: C6H5CH3 + H2 → C6H6 + CH4. Toluene can also be used to producephenol, (C6H5OH), benzoic acid (C6H5COOH), and benzaldehyde (C6H5CHO). Nitratedforms of toluene produce explosive compounds; the most common of these is TNT (SeeTrinitrotoluene).
Definition
ChEBI: The simplest member of the class toluenes consisting of a benzene core which bears a single methyl substituent.
General Description
A clear colorless liquid with a characteristic aromatic odor. Flash point 40°F. Less dense than water (7.2 lb / gal) and insoluble in water. Hence floats on water. Vapors heavier than air. May be toxic by inhalation, ingestion or skin contact. Used in aviation and automotive fuels, as a solvent, and to make other chemicals.
Air & Water Reactions
Highly flammable. Insoluble in water.
Reactivity Profile
Toluene reacts vigorously with allyl chloride or other alkyl halides even at minus 70° C in the presence of ethyl aluminum dichloride or ethyl aluminum sesquichloride. Explosions have been reported [NFPA 491M 1991]. Incompatible with strong oxidizing agents. When added to a tank of sulfur dichloride, the tank over pressurized and ruptured in a reaction thought to be catalyzed by iron or iron(III) chloride [Chem. Eng. News, 1988, 66(32), 2].
Hazard
Flammable, dangerous fire risk. Explosive limits in air 1.27–7%. Toxic by ingestion, inhalation, and skin absorption. Visual impairment, female reproductive effects, and pregnancy loss. Questionable carcinogen.
Health Hazard
Exposures to toluene cause adverse health effects to animals and humans. The symptoms of toxicity and poisoning include, but are not limited to, mild irritation to the skin, headache, nausea, and effects on the CNS. Prolonged exposure to high concentrations of toluene causes disturbances in vision, dizziness, nausea, CNS depression, paresthesia, and sudden collapse. The acute oral LD50 value of toluene in laboratory rats has been reported as 636–7300 mg/kg. Exposure to toluene has been reported to cause rapid and severe corneal damage and conjunctiva infl ammation. The acute dermal LD50 in rabbits was found to be between 1200 and 1400 mg/kg.
Fire Hazard
Toluene is a flammable liquid (NFPA rating = 3), and its vapor can travel a considerable distance to an ignition source and “flash back.” Toluene vapor forms explosive mixtures with air at concentrations of 1.4 to 6.7% (by volume). Hazardous gases produced in fire include carbon monoxide and carbon dioxide. Carbon dioxide and dry chemical extinguishers should be used to fight toluene fires.
Flammability and Explosibility
Toluene is a flammable liquid (NFPA rating = 3), and its vapor can travel a considerable distance to an ignition source and “flash back.” Toluene vapor forms explosive mixtures with air at concentrations of 1.4 to 6.7% (by volume). Hazardous gases produced in fire include carbon monoxide and carbon dioxide. Carbon dioxide and dry chemical extinguishers should be used to fight toluene fires.
Chemical Reactivity
Reactivity with Water No reaction; Reactivity with Common Materials: No reactions; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
Potential Exposure
Toluene is used as an industrial chemical, chemical intermediate; solvent, and emulsifier; may be encountered in the manufacture of benzene. It is also used as a chemical feed for toluene diisocyanate, phenol, benzyl and benzoyl derivatives; benzoic acid; toluene sulfonates; nitrotoluenes, vinyltoluene, and saccharin; as a solvent for paints and coatings; or as a component of automobile and aviation fuels.
Carcinogenicity
The IARC has determined that there is evidence for the lack of carcinogenicity of toluene in experimental animals and that there is inadequate evidence for carcinogenicity in humans. Results of in vitro assays generally indicate that toluene is not genotoxic. Reports of increased incidences of sister chromatid exchanges and chromatid breaks in exposed workers are confounded by concurrent exposure to other organic chemicals.
storage
toluene should be used only in areas free of ignition sources, and quantities greater than 1 liter should be stored in tightly sealed metal containers in areas separate from oxidizers.
Shipping
