Mesitylene or 1,3,5-trimethylbenzene (C9H12) is an aromatic hydrocarbon with three methyl substituents attached to the benzene ring. It is prepared by distillation of acetone with sulfuric acid or by trimerization of propyne in sulfuric acid, which, in both cases, acts as a catalyst and dehydrating agent. It is commonly used as a solvent in research and industry. It is flammable and an irritant; it is a low-freezing liquid.
