Abstract

The isomerization and dehydrogenation of terpinolene, (-)-limonene, α-terpinene over CaO was investigated at 290 and 380 °C. The main products in all cases are α-terpinene, γ-terpinene, 2,4(8)-menthadiene, 3,8(9)-methadiene, and p-cymene. It appears that α- and γ-terpinene are formed in proportions approaching thermodynamic equilibrium. A scheme for the reactions based on the assumption that CaO acts as a basic catalyst is proposed.
