摘　　要：以氯化钙为催化剂 ,苯为带水剂 ,分别以辛醇、十二醇、十四醇、十六醇、十八醇和氯乙酸在回流温度下反应 5h ,合成了相应的氯乙酸高碳脂肪醇酯 ,分别记为化合物 1～ 5。较佳工艺条件为 :n(氯乙酸 )∶n(脂肪醇 ) =1 2∶1,反应温度为 130℃ ,W(催化剂 ) 5 %。通过减压蒸馏提纯了氯乙酸辛酯和氯乙酸十二酯 ,其余三种产物用无水乙醇重结晶。用IR表征了产物的结构。Through the esterifications of chloroacetic acid and the relative fatty alcohol,octy1 chloracetate,dodecy1 chloracetate,tetradecy1 chloracetate,hexadecy1 chloracetate and octadecy1 chloracette(1～5)were synthesized respectively under 3 h reflux Meanwhile CaCl 2 was used as catalyst and benzene was used as removing water reagent which is formed in the esterification The molecular structures of the fatty alcohol chloracetates were characterized by IR
