摘　　要：研究了微波协同大孔树脂催化合成肉桂酸正戊酯和异戊酯的扩大实验。结果显示,合成肉桂酸正戊酯的优化工艺条件为:肉桂酸7.4g,正戊醇17mL,CAT-600大孔树脂6.4g,微波功率400W,反应时间为8min时,酯化率97.23%;合成肉桂酸异戊酯的优化工艺条件为:肉桂酸7.4g,异戊醇19mL,CAT-600大孔树脂8.1g,微波功率700W,反应时间为8min时,酯化率97.01%。the microwave assisted synthesis was integrated with macroporous resin catalysis to prepare n - pentyl and isoamyl cinnamate from cinnamic acid. The enlarged preparation processes were investigated and the optimum synthetic conditions were： cinnamic acid being 7.4 g, n -pentanol being 17 mL, catalyst being CAT - 600 macroporous resin 6.4 g, microwave power being 400 W, reaction time being 8 min, the yield being 97.23 % for n - pentyl cinnamate ; cinnamic acid being 7. 4 g, isopentanol being 19 mL, catalyst being CAT -600 macroporous resin 8.1 g, microwave power being 700 W, reaction time being 8 rain, the yield being 97. 01% for isoamyl cinnamate.
