以4个杂环芳香胺为重氮组分,3个N,N-二氰乙基芳香胺为偶合组分,经重氮化、偶合反应合成了12个杂环-双氰乙基系列偶氮物;采用紫外-可见吸收光谱、红外光谱及核磁共振氢谱等对其结构进行了表征;还考察了它们在涤纶织物、乙酰化杉改性木粉和氰乙基化改性木粉上的染色性能.结果表明,12个偶氮物为目标产物,在N,N-二甲基甲酰胺（DMF）中的最大可见吸收波长为417～621 nm,摩尔吸光系数均大于104.这些化合物染色涤纶织物的色光分属黄色、红色、紫红色和蓝色系列,并具有高水洗牢度和高日晒牢度;染色乙酰化木粉和氰乙基木粉的色光和水洗牢度与染色涤纶织物相近.这12个分散染料具有色谱范围广、色泽鲜艳、高...

Twelve dicyanoethyl-heterocyclic azo disperse dyes were synthesized with four different heterocyclic aromatic amines as the diazo components and three N, N-2-cyanoethyl anilines as the coupling components. They were characterized by UV-Vis, IR and 1H NMR. Their dyeing performance on polyester fabric, acetylated fir powder and cyanoethylated fir powder was also investigated. The results indicate that the maximum visible adsorption of twelve azo components in DMF is over the range of 417-621 nm with the molar absorptivity beyond 104. The shade of dyed polyester fabric includes yellow, red, reddi...
