Paragraph 0016; 0017; 0018, (2017/08/28)
The invention relates to a method of synthesis of N-alkyl p-toluene sulfonamide. In the presence of a PIMs supported solid super acid catalyst, a reaction between anhydrous p-toluene sulfonamide and a primary amine is carried out in the presence of a water absorber 5A-type molecular sieve to obtain a target product. The conversion rate of the anhydrous p-toluene sulfonamide reaches 81.90%, and the yield of the N-alkyl p-toluene sulfonamide can reach 70.53%. The method has high catalyst yield and mild reaction conditions. The catalyst is easy to recycle. The method is low in environment pollution.
