摘要
以含吸电子取代基的芳伯胺为原料,双氧水作氧化剂,在弱酸性介质中,在偶氮基的邻位引入配位基合成媒介染料。通过对产物结构分析和性能测定,确定了该方法的最佳工艺条件。
The feasibility of synthesizing mordant dyes through oxidation beside azo group on O′-hy-droxy azo dyes is discussed and the factors affacting the oxidation reactions are investigated.Its tech-nological process is confirmed through analysing oxidational product structures,testing its abilitiesand comparing with standard sample。
