摘　　要：以固体酸催化合成了氯乙酸异辛酯。经实验确定的最佳反应条件为 :醇酸的量比为 1 0∶1 0 ,固体酸用量为反应物总质量的 2 0 % ,反应时间为 1～ 2h ,酯化率达 96 8%。该催化剂后处理简单 ,不腐蚀设备 ,无环境污染 ,催化活性稳定 ,无须再生处理 ,经重复使用Solid acid was used as catalyst for the synthesis isooctyl chloroacetate.The yield of esterification reached 96.8% under the optimum reaction conditions that the molar ratio of alcohol to acid was 1.0∶1.0,the amount of catalyst was about 2.0% of the mass of reaction mixture,and the reaction time was 1-2 h.This solid acid catalyst for the esterification has many advantages such as simple post-treatment,being non-corrosive to the equipment and no pollution.Its catalytic activity didn't decrease after being repeatedly used for 30 times.
