摘要
以蓖麻油为原料，无溶剂条件下经微波辐射裂解制备癸二酸，最佳工艺条件为：氢氧化钠（g）：蓖麻油（g）=1．5:1．0，碱浓度为55．6％，微波功率为160W，裂解时间22min，癸二酸产率达96．5％，与传统方法比较，反应时间缩短了30倍，节约了能耗，减少了污染，降低了成本．
To catalyze the sebacic acid from the cracking of castor oil by microwave irradiation under the sovent-free condition,the optimum reaction conditions are as follows: the reaction ratio of sodium hydroxide to castor oil is 1. 5: 1. 0,the concentration of sodium bydroxide being 55. 6%,microwave power and microwave irradiation time bcing 160 W, 22 min respectively,and the yield of sebacic acid can reach 96. 5% under the optimum condition. Compared with the traditional method, it has some advantages such as shorter reaction time, lower energy consumption, lower cost and benign to environment.
