摘　　要：报道了以酸性多级孔ZSM-5沸石为催化剂,以二苯甲醇和对甲基苯磺酰胺为原料,实现磺酰胺的N-烷基化反应制备N-取代的酰胺化合物,同时进行反应条件的筛选(溶剂,温度,催化剂的量),最终确定该反应的最优条件。研究发现,以1,2-二氯乙烷为溶剂,80oC下N2氛围下,反应6 h获得最高的产物收率。Using benzhydrol and p-touenesulfonamide as raw materials, acidic porous ZSM-5 zeolite as catalyst, N-substituted amide was prepared via N-alkylation of sulfonamide. Meanwhile, the optimal reaction conditions were determined, including solvent, temperature and catalyst dosage. The experiment results show that, when 1,2-dichloroethane is used as solvent, at 80 ℃ in N2 atmosphere, reaction time is 6 h, the product yield is the highest.
