摘　　要：对2-氯-5-氯甲基吡啶生产工艺中丙烯腈及含丙烯腈溶液中微量水分去除方法进行了试验,选择了使用3A分子筛进行脱水的方法,并运用到生产实践中,该方法具有常温吸附除水的特点,可避免除水过程中丙烯腈聚合。The removal of trace water in acrylonitrile and acrylonitrile solution in the manufacturing process of 2-chloro-5-chloromethylpyridine was investigated.The method of dehydration with 3A molecular sieve was selected and applied to the production practice.The method has the advantage of removing water at room temperature and avoids the polymerization of acrylonitrile in the water removal process.
