toluene's Usage Examples:

Three isomers exist, the orthoand para-compounds being the chief products of the direct nitration of toluene.

The light oil fraction of the coal-tar distillate, which comes over below 140° and consists principally of benzene, toluene and the xylenes, yields on fractionation (i) various volatile impurities such as carbon disulphide, (2) the benzene fraction boiling at about 80° C.

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 based scintillator.

Para-xylene is obtained when camphor is distilled with zinc chloride, but it is best prepared from para-brom-toluene or dibrombenzene, methyl iodide and sodium.

Technically it is prepared from toluene, by converting it into benzyl chloride, which is then heated with lead nitrate: C 6 H 5 CH 2 C1 +Pb (N03)2 2NO 2 +PbC1.

It is excreted when many aromatic compounds, such as benzoic acid and toluene, are taken internally.

Meta-nitrotoluene (melting at 16° C.

Phenylnitromethane, C 6 H 5 CH 2 NO 2, isomeric with the nitrotoluenes, is prepared by the action of benzyl chloride on silver nitrite.

Meta-nitrotoluene (melting at 16° C.

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.

It can be prepared by the oxidation of toluene, benzyl alcohol, benzaldehyde and cinnamic acid; by the oxidation of benzene with manganese dioxide and concentrated sulphuric acid in the cold (L.
