摘要
工业莰烯在耐高温离子交换树脂DCP催化作用下与无水乙醇反应生成了异龙脑基乙醚。探索了反应温度、反应时间、催化剂用量,以及工业莰烯与无水乙醇的配比对反应的影响。结果表明,异龙脑基乙醚合成的优化条件为:m(工业莰烯)∶m(无水乙醇)=10∶7-10∶9,DCP用量占物料总质量的15%,反应温度(75±1)℃,反应时间6-9 h,工业莰烯转化率达到71.5%,选择性达到96.8%。
Isobornyl ethyl ether was prepared by ethoxylation of camphene with absolute ethanol in the presence of DCP heatresistant ion exchange resin. The optimum reaction conditions are as follows: mass ratio of camphene to absolute ethanol is 10:7 - 10:9, the mass ratio of catalyst to total is 15 % , reaction temperature is (75 ± 1 )℃ and reaction time is 6-9 h. Under the optimum conditions the conversion of camphene is 71.5 % and the selectivity of the main product is 96.8 %.
