1.The optimum synthetic conditions of ethyl chloroacetate are: molar ratio of chloroacetic acid to ethanol is 1:8, the quantity of catalyst[Fe2(SO4)3 xH2O] is 10% of the mass of chloroacetic acid, reaction time is 1 hour, 5A zeolite was used as dehydrating agent. In these conditions, the yield of ethyl chloroacetate was up to 73%.
用Fe_2(SO_4)_3·xH_2O作为催化剂合成氯乙酸乙酯的较佳反应条件是:酸醇物质的量之比为1:8,催化剂用量为氯乙酸质量的10%,以5A分子筛作为脱水剂,回流时间1h,收率达73%以上。收藏指正
