摘　　要：考察了以丙酮作溶剂,蒎烯在固体磺酸D-72催化剂上一步水合反应的动力学规律,发现溶剂和水用量对催化性能有较大的调节作用,在丙酮与蒎烯不同的体积比下,α-松油醇选择性和总醇选择性都是随着蒎烯转化率的升高而降低。当反应温度为60℃,丙酮/蒎烯体积比2∶1、蒎烯/水物质的量比为1∶4条件下,适当控制反应时间,α-松油醇选择性可达到50%以上,总醇选择性可达到60%以上。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.
