As such, its systematic IUPAC name is methylbenzene. Toluene is predominantly used as an industrial feedstock and a solvent. As the solvent in some types of paint thinner, permanent markers, contact cement and certain types of glue, toluene is sometimes used as a recreational inhalant [16] and has the potential of causing severe neurological ...
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.
The production of p-xylene is industrially significant, with annual demand estimated at 37 million tons in 2014, and still on the increase. [12] [13] p-Xylene is produced by catalytic reforming of petroleum naphtha as part of the BTX aromatics (benzene, toluene and the xylene isomers) extracted from the catalytic reformate.
Xylene is used in the laboratory to make baths with dry ice to cool reaction vessels, [17] and as a solvent to remove synthetic immersion oil from the microscope objective in light microscopy. [18] In histology, xylene is the most widely used clearing agent. [19] Xylene is used to remove paraffin from dried microscope slides prior to staining.
It is used in jet fuel, mixed with other hydrocarbons, to prevent the formation of solid particles which might damage the engine.
