摘要
在自制反应装置中，以己二酸为催化剂，考察了各种因素对甘油氯化制备二氯丙醇反应的影响。实验结果表明，甘油氯化的较优条件是：催化剂己二酸用量为甘油质量的6％～7％，反应温度110～120％，带水剂甲苯，二氯丙醇的收率达到90％。催化剂己二酸重复使用5次活性不下降。
In our self-made reactor, the influence of various factors to prepare reaction of glycerol chloride system is inspected. The experimental result shows the optimum conditions of chlorination of glycerol as follows： the catalyst dosage of glycerol adipate meets the quality of 6%-7%, reaction temperature meets 110~120~C , the water-entrainer toluene, two chlorine propanol yield reached 90%. The catalyst can be reused 5 times without activity of adipic acid decreased.
