Description: Toluene is a mono-aromatic hydrocarbon mainly obtained from petroleum refining and coal carbonization. It is a widely used organic solvent with excellent solvency for oils, resins, rubber, coatings, inks and adhesives. It also serves as an important intermediate for organic synthesis. It is highly flammable and its vapor can form explosive mixtures with air. Excessive inhalation may cause damage to the nervous system and respiratory tract.
