摘　　要：在微波辐射下,以氨基磺酸为催化剂,由氯乙酸和异辛醇合成氯乙酸异辛酯。讨论了微波功率、醇酸物质的量比、催化剂用量、反应时间等因素对反应的影响。通过实验得到最佳反应条件为:微波功率为528 W,醇酸物质的量比1.4︰1,催化剂用量1.5 g(相对于0.1 mol氯乙酸),反应时间25 min,此反应条件下的氯乙酸酯化率可达96.2%。Under microwave radiation,isooctyl chloroacetate was synthesized from chloroacetic acid and isooctyl alcohol by using sulfamic acid as catalyst.Effects of microwave power,ratio of alcohol to acid,reaction time,catalyst dosage on the reaction were discussed.Through a series of experiments,the optimum conditions were determined as follows,the radiation power 528 W,the ratio of alcohol to acid 1.4︰1,reaction time 25 min,the catalyst dosage 1.5 g（when the amount of chloroacetic acid is 0.1 mol）.Under above conditions,the esterification rate of chloroacetic acid can reach to 96.2%.
