WebbThe vapour pressures of benzene, toluene, ethylbenzene, and the three xylenes have been measured between their normal boiling points and their critical temperatures by both dynamic and static methods. Trial was made of several equations proposed for the representation of the vapour pressure–temperature relationship Toluene , also known as toluol (/ˈtɒl.ju.ɒl, -ɔːl, -oʊl/), is a substituted aromatic hydrocarbon. It is a colorless, water-insoluble liquid with the smell associated with paint thinners. It is a mono-substituted benzene derivative, consisting of a methyl group (CH3) attached to a phenyl group. As such, its systematic IUPAC name is methylbenzene. Toluene is predominantly used as an industrial feedstock and a solvent.
