摘　　要：对甘油制备二氯丙醇的合成工艺进行了研究。重点考察了反应时间、反应温度、催化剂含量等因素,并获得了适宜的反应条件为温度105℃,反应时间4h,催化剂为乙酸,催化剂含量8%(w/w)。运用气相色谱法测定甘油氯化反应得到的二氯丙醇,得到的1,3-二氯-2-丙醇的回归方程为A=0.2123ρ-0.1334。The effect of different factors on chlorination of glycerol was investigated.The optimal conditions for the chlorination of glycerol obtained from experimental results were as follows：the temperature is 105℃,the catalyst was anhydrous acetic acid,the catalyst loading is 8%（w/w）,reaction time was 4h.A simple gas chromatographic method for the identification of dichloropropanol was described, and the dichloropropanol regression equation is A=0.2123ρ-0.1334.
