Synthesis of Azo Disperse Dyestuff Based on Depolymerization of Waste Polyester Fiber by Ethylene Glycol

Keywords： waste polyester fiber , alcoholysis , bis(2-hydroxyethyl)terephthalate , azo disperse dyestuff

以乙二醇为解聚剂,醇解废弃聚酯纤维得到中间产物对苯二甲酸乙二醇酯(BHET)单体,再经过硝化、还原、重氮反应得到重氮盐,重氮盐与1-(4-磺酸苯基)-3-甲基-5-吡唑啉酮偶合制备偶氮分散染料,可用于涤纶、锦纶等纤维及其制品的染色,实现废弃聚酯的资源化再利用.合成的染料呈黄色,与其紫外光谱中最大吸收波长为395～398nm相符.将合成的染料配制为pH值3.5～6.0的染液对锦纶长丝染色,并分析了不同pH值条件下的上染率和L*、a*、b*值.
