摘　　要：杂环类偶氮分散染料具有色光鲜艳、发色强度高、牢度性能好、深色效应好、摩尔消光系数高等诸多优良性能,在分散染料中占有不可或缺的地位。本文采用2-氨基-6-甲氧基苯并噻唑作为重氮组分,合成了7支偶氮型分散染料(D-1~D-7)。结果表明,D-4具有最大的摩尔消光系数,达5万以上;D-2、D-3、D-4、D-5具有较高的上染率,D-2具有优良的提升力;7支染料都具有优良的耐洗色牢度,基本上都能达到5级。Heterocyclic azo disperse dyes occupied the indispensable positions in dyes industry due to their novel performance, such as bright color shade, high coloring intensity, excellent fastness, deep color effect, high molar extinction coefficient, etc. Seven beterocyclic azo disperse dyes （D-1 ~ D-7） were synthesized from 2-amino-6-methoxybenzothiazole and seven different intermediates by diazotization and coupling. The results showed that D-4 has the highest molar extinction coefficient, up to 50 000 L · mo1-1 · cm-1. D- 2, D-3, D-4, and D-5, have excellent dye uptake; and D-2 has very good build up. Seven dyes have wonderful color fastness to washing, all of them about 5 grade.
