4,4′-二氨基二苯胺-2-磺酸在环保型直接染料中应用的探讨

A Discussion on the Applicatioin of 4,4'-Diaminodiphenylamine-2-sulfonic Acid in Environmental protection Direct Dyes

本文重点介绍了以4,4-二氨基二苯胺-2-磺酸(简称p,p’-酸)为主要原料在小试中来合成一系列环保型直接染料。为今后生产替代联苯胺系列的直接染料开拓了思路。

A series of eco -friendly direct dyes were synthesized using 4,4′-diaminodiphenylamine -2 -sulfonic acid as starting mate- rial. These dyes provided a new idea for the production of alternatives for benzidine - based direct dyes.
