摘　　要：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,1HNMR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类似,但稍暗。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 results show that the maximum absorption of these five azo disperse dyes is in the range of 513 nm and 655 nm(acetone).The shade of the dyed polyester fabric with high soaping fastness and high light fastness is blue-green,brilliant green,red,blue-purple,and blue-purple,respectively.The shade of the dyed acetylated wood flour and benzyl wood flour is similar to that of the dyed polyester,but it is darker than that of dyed polyester.
