Abstract:An improved process for the synthesis of 4 -terpenol through three steps including epoxidation, ring opening rearrangement and selective hydrogenation was reported. Starting from terpinene (4), peroxyacetic acid was prepared with cheap hydrogen peroxide and acetic acid. Epoxy terpinene (3) was obtained by oxidation; 1 - isopropenyl-4-methyl-cyclohexane-3-enol(2) was obtained by epoxy ring opening rearrangement catalyzed by nano alumina in 2-methyltetrahydrofuran solvent, and then 2 was selectively hydrogenated with platinum dioxide in ethyl acetate to obtain 4 -terpineol (1). The total yield of this process was of 37%, and a purity of more than 98% was obtained after purification, which met the requirements for commercialization.
Key words:4-terpineol; nano-alumina; epoxide rearrangement; hydrogenation
