| Abstract: | Aromatic hydrazine 4-(2-N, N-dimethylamino-ethyl)sulfonyl - phenyl hydrazine is the important intermediate of cationic fluorescent whitener CH, it can be prepared from the para-ester as the raw material and through hydrolysis, amination, diazotization, reduction processes as introduced in this paper. Tin chloride was used as the catalyst to improve the yield (85%) of the product in the process of reduction, and the structure of the product was verified by IR, NMR, Elem Anal and melting point apparatus. |
