There is some evidence that low-level toluene exposure may cause disruption in the differentiation of astrocyte precursor cells. [27] This does not appear to be a major hazard to adults; however, exposure of pregnant women to toluene during critical stages of fetal development could cause serious disruption to neuronal development. [27]
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. [39] Toluene is a common solvent, e.g. for paints, paint thinners, silicone sealants, [40] many chemical reactants, rubber, printing ink, adhesives (glues), lacquers, leather tanners, and ...
The simplest member, toluene (or methylbenzene), has the hydrogen atom of the benzene ring replaced by a methyl group. The chemical formula of alkylbenzenes is C n H 2n-6. [2] Safety hazards of toluene. Oftentimes, toluene is used as an organic solvent.

Toluene diisocyanate (TDI) is an organic compound with the formula CH 3 C 6 H 3 (NCO) 2. Two of the six possible isomers are commercially important: 2,4-TDI (CAS: 584-84-9) and 2,6-TDI (CAS: 91-08-7). 2,4-TDI is produced in the pure state, but TDI is often marketed as 80/20 and 65/35 mixtures of the 2,4 and 2,6 isomers respectively.
Hazard statements. H302, H340, H350, H361, ... It is made by nitrating toluene at above -10 °C. This reaction affords a 2:1 mixture of 2-nitro and 4-nitro isomers. [4]
2,5-Diaminotoluene is prepared through electrolytic reduction of 2,5-dinitrotoluene. [3] Other methods include the reductive cleavage of 4-amino-2,3'-dimethylazobenzene as well as the condensation of 2-amino-1-methylbenzene and toluene-4-sulphonyl chloride to produce 4-toluenesulphono-2-toluidide which is then coupled with diazotized aminobenzenesulphonic acid and reduced.
Sharkey Landfill is a 90-acre property located in New Jersey along the Rockaway and Whippany rivers in Parsippany, New Jersey. Landfill operations began in 1945, and continued until September 1972, when large amounts of toluene, benzene, chloroform, dichloroethylene, and methylene chloride were found, all of which have are a hazard to human health causing cancer and organ failure.
