\-əˌwēn\ noun
(-s)
Etymology: International Scientific Vocabulary tol- + -ene
: a light mobile liquid aromatic hydrocarbon C6H5CH3 that resembles benzene but is less volatile, less flammable, and less toxic, that was obtained originally by distilling balsam of tolu, that is produced commercially from light oils from coke-oven gas and coal tar and especially since World War II from petroleum (as by dehydrogenation of methyl-cyclohexane or by the reforming of dimethylcyclopentane), and that is used chiefly as a solvent, as a raw material for trinitrotoluene, dyes, pharmaceuticals, and other organic compounds, and as a blending agent for gasoline especially for use in aviation because of its high antiknock property — called also methylbenzene |
