摘　　要：采用自制的硫酸高铈改性阳离子交换树脂催化合成衣康酸二甲酯,考察了催化剂用量、醇酸物质的量比、反应时间、催化剂重复使用次数及带水剂等因素对收率的影响。结果表明该催化剂具有催化活性高,易分离回收,有一定的重复使用性等优势。适宜条件下衣康酸二甲酯收率可达93.8%。By using cation exchange resin modified cerium sulfate as the catalyst, itaconate acid and methanol reacted to form dimethyl itaconate. Some effects were investigated such as amount of catalyst,reaction time,molar ratio of alcohol to acid, different carrying water agents and repeated uses.Experimental results showed that cation exchange resin modified cerium sulfate was the efficient and economic catalyst.Under the best conditions, dimethyl itaconate yield could reach 93.8 %.
