| 摘 要： | 研究了在固体酸催化剂存在下，２，１０－环氧蒎烷液相重排反应的产物分布规律，考察了反应温度、反应时间、溶剂用量对重排反应的影响。结果表明：２，１０－环氧蒎烷液相重排主要生成紫苏醇和桃金娘烯醇，以硝酸铵作催化剂，硝基甲烷作溶剂，２，１０－环氧蒎烷于８０～９０℃可定向重排生成紫苏醇，转化率达９８．９％，紫苏醇选择性８８．１％。

| Abstract: | The product distributions of liquid isomerization of 2,10 epoxypinane in the presence of acid catalyst was studied.The influence of reaction temperature,reaction time and the amount of solvent on the isomerization were investigated.It is discovered that the isomerization of 2,10 epoxypinane produced mainly perilly alcohol and myrentol.Perilly alcohol can be obtained from isomerization of 2,10 epoxypinane catalyzed by NH 4NO 3 in CH 3NO 2 with 98 9% conversion and 88 1% selection. |
