摘要
研究了Ｄ－７２离子交换树脂催化剂催化α－蒎烯在丙醇中的烷氧基化，α－松油基丙醚为主要加成产物，占烷氧基化加成产物选择性总和的５０％．考察了反应温度、时间对反应的影响．动力学研究表明，α－蒎烯在丙醇中的转化服从准一级反应动力学模式．测得反应的活化能为５６．６４ｋＪ／ｍｏｌ，频率因子ｋ０为１１．４×１０８ｈ－１．
The alkoxylation of α pinene in propanol catalyzed by D 72 ion exchang resin was studied in this paper, α propyl terpinyl ether is a major addition product, which contains 50 percent of total selection of alkoxylation addition products. Effects of reaction temperature and time were investigated.It is proved that the conversion of α pinene in propanol is keeping with first order reaction model.It is measured that the activaction energy is 56.64 kJ/mol and the frequency factor is 11.4×10 8 h -1 .
