摘　　要：针对氯乙酸甲酯精馏塔塔釜液中水和氯乙酸甲酯的二元体系,采用安托因方程、Clapeyron方程、OrrickErbar法和图解法对塔板数进行了计算,得出精馏塔的理论塔板数为7块,实际塔板数34块,全塔效率0.21,并根据计算结果设计了带有"液-液分离器"的氯乙酸甲酯精馏装置,取得了很好的应用效果.Aiming at the binary system of water and methyl chloroacetate in the tower kettle liquid of methyl chloroacetate distillation column,the number of plate was calculated by Antoine equation,Clapeyron equation,Orrick-Erbar method and graphic method.The theoretical plate number of distillation column was 7,the actual plate number was 34 and the whole tower efficiency was 0.21.According to the calculated results,a methyl chloroacetate industrial distillation system with"liquid-liquid separator"was designed,and good application results have been obtained.
