含氰基偶氮分散染料合成的新方法
摘要:
含氰基偶氮分散染料指
=N-
-NR1R2(环上还可有其它基团),氰基的存在可改善染料的耐光和耐升华牢度,并加深其颜色[1]。染料合成的关键步骤是CN基的引入。比较成熟的方法是由相应的卤代物与氰化亚铜作用[2-5]。由于氰化物的污染,近几年来出现了一些将芳卤转化为芳腈的新方法[6-8]。

A NEW METHOD FOR SYNTHESS OF CYANO DIAZO DISPERSE DYE
Abstract:
A new geen-blue cyano diazo disperse dye has been synthesized by using formamide and acetic anhydride as cyanating agent. Some parameters on the synthesis are studied., A new geen-blue cyano diazo disperse dye has been synthesized by using formamide and acetic anhydride as cyanating agent. Some parameters on the synthesis are studied.
