Abstract

Abstract: Kinetic effects on one-step hydration of pinene in acetone as solvent over D-72 solid sulfonic acid resin as catalyst were investigated. It was found that the amounts of solvent and water possessed strong effect to the catalytic performance, and the selectivity of both α-terpinol and total alcohols was decreased with the increasing of the conversion of pinene under different volume ratio of acetone to pinene. The selectivity of α-terpinol and the selectivity of total alcohol got up to 50 % and 60 % respectively when the reaction temperature was 60 ℃, volume ratio of acetone to α-pinene was 2:1, molar ratio of α-pinene to water was 1:4, under suitable control of reaction time.

Key words: pinene, α-terpinol, catalysis, hydration, solid acid
