摘要
在一定条件下，蒎烯可高选择地氢化成顺式蒎烷，选择性的大小与催化剂的特性及蒎烯的分子构形^（［１］［２］）有关。采用含量高的顺式蒎烯为原料，在适宜的温度、氢压及搅拌条件下，改变催化剂的某些特性能提高加氢所得蒎烷的顺式含量。以顺式 ９７． ８４％、反式 １． ９６％的蒎烯为原料，采取 Ｗ－６型雷尼镍与 ＭＸ~＊助催化剂联用的条件下氢化，所得蒎烷总含量 ９９． ６９％，其中顺式蒎烷含量 ９６． １５％。
Pinene can be high-selectively Hydrogenated to cis-pinane under optimum conditions. The degree of selectivity is re- lated to properties of catalysts and forms of pinene molecules. Using cis-(97. 84 % ) and trans- (1. 96% ) pinene as raw materials, hydrogenated in the presence of W-6 Raney nickel and MX as cocatalyst. the total yield of pinane gained is 99. 69 %. among those the content of cis-pinane is 96. 15 %.
