-
摘要: 为了研究光降解产物及机理,筛选不含产生致癌物、具有优异的日晒和湿处理牢度的代用偶氮染料,设计并合成了21种H-酸偶氮染料,以1H-NMR和紫外可见光谱对染料结构进行了表征。Abstract: In order to investigate the mechanism and intermediates of light degradation, select some low toxic, high light and wet fastness substitutes for the prohibited dyes, 21 kinds of azo dyes have been designed and synthesized. All these dyes were characterized by UV visible and 1H NMR spectra.
