含羧甲磺酰基水暂溶性分散染料的研究──几个中间体及染料的合成

A Study on Temporarily Water-Soluble Disperse Dyes Containing Carboxymethylsulfonyl Group──The Synthesis or Intermediates and Dyes

用氯磺化法或硫醚氧化法结合成出８个中间体，并以其作为重氮组分，合成出１０个新的含羧甲磺酰基水暂溶性分散染料。

Four new intermediates containing carboxymethylsulfonyl group were synthesized by the methods via chlorosulfonation of acetanilides or oxydation of thioethers. Intermediate (1) was synthesized by oxidation of thioether. Intermediates 3 and 4 were synthesized by chlorosulfonation of acetanilides. Intermediate 2 can be prepared by either methods. Intermediates 1 to 4 and other intermediate compounds were analyzed by IR and elementary analysis. Four new and other six temporarily water-soluble azo dyes containing carboxymethylsulfonyl group in diazo component were prepared. Their absorption specra were obtained.
