Compounds derived by substituting aliphatic radicals in the benzene nucleus; such a compound is methylbenzene or toluene, C 6 H 5 CH 3.
Toluene or mono-methylbenzene results from the pyrocondensation of a mixture of acetylene and allylene.
A similar contradiction apparently exists with regard to the specific volume, for while benzene has a specific volume correspinding to Claus' formula, toluene, or methylbenzene, rather points to Kekule's.
An important oxidation synthesis of aromatic acids is from hydrocarbons with aliphatic side chains; thus toluene, or methylbenzene, yields benzoic acid, the xylenes, or dimethyl-benzene, yield methyl-benzoic acids and phthalic acids.
TOLUENE, Or Methylbenzene, C7H8 Or C6H5 CH 3, an aromatic hydrocarbon; the first homologue of benzene.
