摘要
用硼化镍催化剂常压催化氢化α-蒎烯,生成的蒎烷产率高达95％;顺式蒎烷的选择性为97％,α-蒎烯的转化率为100％。
Pinanes are practically synthesized from a-pinene by catalytic hydrogenation in the presence of the raney-Ni or other catalyst at a higher pressure and temperature.In order to work out a convenient procedure for the synthesis, the catalysts P-1. 00-Ni and P-2. 00-Ni, and their modifications P-1. 00-Ni-Pd and P-2. 00-Ni-Pd were put on trials. It was found that these catalysts were all efficient in the hydrogenation of a-pinene to give cis-pinane at atmophere pressure and ordinary temperature. The yield was around 95％, the selectivity to cis-pinane was usually over 97％ and the conversion rate of a-pinene was appoximately 100％. A few percent of Pd comprised in the catalyst would accelerate the reaction and increase the yield.
