【摘要】研究了硝酸铵催化剂体系和溶剂对2,10-环氧蒎烷液相重排反应的影响.重点考察了催化剂分散状态、溶剂性质及溶剂用量对重排产物分布的影响.实验结果表明:用硅胶吸附的硝酸铵具有较好的活性,强极性的硝基甲烷溶剂中对于紫苏醇的选择性最好,而弱极性的氯仿和1,1,1-三氯乙烷则有利于桃金娘烯醇的生成.更多还原

【Abstract】 The products distribution of liquid isomerization of 2,10-epoxypiane in the presence of NH₄NO₃ was studied in this paper.The influences of different catalyst systems,solvents and the amount of solvent on the isomerization were investigated.It is discovered that perilly alcohol can be obtained in a high selectivity by NH₄NO₃ which is absorbed on silica gel in CH₃NO₂,but myrtenol was obtained as the main product catalyzed by NH₄NO₃ in CHCl₃ and CCl₃CH₃.更多还原
