Description
Colorless liquid solvent with a Benzene odor. Toluene is produced from the fractional distillation of coal tar. It is used as a solvent for paint, coatings, resins, as well as for most oils, rubber, polymers, and adhesives. Toluene is also used as a component in aviation fuel and for the manufacture of dyestuffs and explosives. Industrial grade toluene has been called toluol.
Synonyms and Related Terms
toluol; methylbenzene; phenylmethane; methyl benzene
