リモネンの高温接觸變化について

抄録

Catalytic change of limonene, with metallic catalysts, such as those having Cu, Ni and alkali hydroxides, at 260-360° resulted in obtaining terpinolene, α- and γ-terpinene, menthene-1, menthene-3, cymene and menthane, as well as compounds thought to be acetone, toluene and p-ethyltoluene. It has been revealed by this experiment that limonene, through terpinolene and terpinene, is dehydrogenated to cymene and that menthane is formed by the hydrogenation of terpinene to menthene which is subsquently hydrogenated to menthane. Acetone and toluene are directly formed from terpinolene and p-ethyltoluene.
