以3-(N,N-二乙酸乙酯基)氨基-4-甲氧基乙酰苯胺为偶合组份,2-氨基-3,5-二硝基噻吩、3-氨基-5-硝基-2,1-苯并异噻唑、4-硝基苯胺、2,4-二硝基-6-氯苯胺和2,4-二硝基-6-溴苯胺为重氮组分,经重氮化-偶合反应合成了5个二乙酸乙酯基系列偶氮分散染料;用UV-Vis,IR,1 HNMR和MS对其进行结构表征,并探索其对涤纶织物和改性木粉的染色性能.结果表明:所合成的5个二乙酸乙酯基系列偶氮分散染料为目标产物,其最大可见吸收波长为513～655 nm(丙酮);染色涤纶织物的色光分别为蓝绿色、艳绿色、红色、蓝紫色和蓝紫色,并体现高皂洗牢度和高日晒牢度特征;染色乙酰化木粉和染色苄基化木粉的色光与染色涤纶织物的色光...

In this work,we report our recent study results where five ethyl diacetate group azo disperse dyes successfully were synthesized by the diazotization coupling reaction with 3-(N,N-ethyl diacetate group)amino-4-methoxyacetaniline as the coupling component and 2-amino-3,5-dinitrothiophene,3-amino-5-nitro-2,1-benzoisothiazole,4-nitroaniline,2,4-dinitro-6-chloroaniline and 2,4-dinitro-6-bromoani-line as the diazo componentts.Their structures were characterized by UV-Vis,IR,1HNMR and MS results,and then we examined their dyeing performance for both polyester fabric and modified wood flour.Our resul...
