Abstract

Camphene is obtained by isomerizing pinene (e.g. a mixture of a - and b -pinenes) in the vapour phase in admixture with an inert gas (e.g. N2) and in the presence of a catalyst in suspension. Suitable catalysts are TiO2, boric acid, salicylic acid, picric acid or activated clay, and the carrier may be a terpene, e.g. camphene itself. The reaction temperature may be 100-160 DEG C. and the process may be continuous.
