摘　　要：芳香肼4-(2-N,N-二甲氨基-乙基)磺酰基-苯肼是阳离子荧光增白剂CH制备的重要中间体,采用对位酯为原料,经过水解,加胺得到芳香胺,再经重氮化、还原的合成路线得到。还原过程中采用氯化亚锡作为还原剂提高芳香肼的收率(85%)。用熔点、红外、核磁、元素分析对产品结构进行表证。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.
