4,4′-二氨基苯甲酰替苯胺系列偶氮染料的合成及应用

Studies on synthesis and application of series dyes containing benzoylamido link as groups

选定 4,4′ 二氨基苯甲酰替苯胺为重氮组分 ,以水杨酸、γ酸为偶合组分 ,控制一定反应条件 ,合成了红棕色、红色、紫色苯甲酰替苯胺型系列直接染料 ,并在铬羊皮上作染色试验 ,染成的有色革具有较高的耐磨擦坚牢度和较高的日晒牢度。

Brown,red,purple series direct dyestuff is synthesized in which diazo component consist of 4,4' diamino benzoylaniline,coupling component consist of salicylic acid,γ acid.The series dyestuff synthesized are applied to sheep chrome leather.The leathers dyed in these dyestuffs have good rubbing fastness and high fastness to light.
