2,3-二氯-6-羧酰氯喹啰啉活性染料反应活性及“染料-纤维”键的稳定性

Study on Reactivity and Stability of “Dye fiber” Linkage of Quinoxaline Reactive Dye

对２，３－二氯－６－羧酰氯喹啉类活性染料的反应活泼性以及“染料－纤维”键的稳定性进行了反应动力学研究，测定水解速度常数；与其他类型活性染料进行比较，对此类活性染料性能进行了评价。

The kinetics of the reactivity and the stability of “dye fiber” linkage were studied. The hydrolysis constant had been determined. The result shows that this reactive dye based upon 2,3 dichloro 6 quinoxaline carbonyl chloride is extremely suitable for exhaust dyeing of cellulosic fibers.
