Uses and applications

What the substance is used for, by industry and function

Solvents, synthetic-resin manufacture, metal polishes, organic synthesis (Cymenes).

How it is made

Mixtures of 3-isopropyltoluene (m-cymene) and 4-isopropyltoluene (p-cymene) can be obtained by propylation of toluene in the presence of an isomerization-active Friedel-Crafts catalyst. These two isomers can be separated by distillation only with difficulty.

Usually prepared by alkylation of toluene, meta-, ortho- and para-isomers obtained ... Separation of the three isomers by gas chromatography.
