摘要
介绍了以苯酐、C l2为原料,无水FeC l3做催化剂,制备单氯代苯酐的方法,从苯酐的转化率、单氯代苯酐选择性两方面展开了苯酐氯化制备单氯代的研究,指出最佳的制备条件为:催化剂用量1.5%,C l2与苯酐摩尔比0.8∶1,反应时间11h。
The preparation of monochlorophthalic anhydride with anhydride and chlorine as row materials was studied from two sides which were the conversion of anhydride and the selectivity of monochlorophthalic anhydride. The best conditions were determined, the catalyst is 1.5% , tool ratio of chlorine and anhydride is 0. 8 ： 1, reaction time is 11 hours.
