研究了在鼓泡式反应柱中生物甘油催化氯化制备二氯丙醇。考察了乙酸、丙酸、丙二酸、己二酸、γ-丁内酯为催化剂以及分别与氯乙酸组成复合催化剂时,反应温度、催化剂量、原料浓度对二氯丙醇收率的影响。研究结果表明:以丙酸和氯乙酸组成的复合催化剂,催化剂总量为甘油的3%,反应温度110℃,原料甘油纯度40%以上,氯化反应15h后,二氯丙醇收率达92.2%。 The catalytic chlorination of glycerol in a bubble column was studied to prepare dichloropropanol. The effects of reaction temperature, catalyst amount and feed concentration on the yield of dichloropropanol were investigated when acetic acid, propionic acid, malonic acid, adipic acid and γ-butyrolactone as catalysts and the composite catalysts with chloroacetic acid respectively. The results showed that the total amount of catalyst was 3% of glycerol, the reaction temperature was 110 ℃, the purity of glycerol was above 40%, and the yield of dichloropropanol was 92.2 after chlorination for 15h %.
