STUDY ON HYDROGENATION OF α-PINENE TO CIS-PINANE CATALYZED BY NANOMETER NICKEL

将纳米镍催化剂首次应用于α-蒎烯的氢化反应中,与其他催化剂相比,本实验条件下原料转化率高于骨架镍,产物顺式蒎烷选择性高于Pd/C。对影响纳米镍催化下α-蒎烯加氢反应制备顺式蒎烷的因素进行了讨论,得出适宜的反应条件:温度90℃,压力4.0MPa,催化剂用量1.0%(质量分数),原料α-蒎烯转化率达100%,产物顺式蒎烷选择性94.3%。

Nanometer nickel was first used in hydrogenation of α-pinene： the conversion rate of raw material with nanometer nickel as catalyst was higher than that of Raney nickel and the selectivity of cis-pinane was higher than that with Pd/C. The suitable conditions of preparing c/s-pinane by hydrogenation of α-pinene catalyzed by nanometer nickel were as follows ： temperature 90℃, pressure 4.0 MPa, and dosage of catalyst 1.0 % （ based on the mass fraction of α-pinene）. The conversion rate of a-pinene was 100 %,and the selectivity of cis-pinane was 94.3 % o
