摘要
将2-氨基苯酚-4-(2'-羧基)磺酰苯胺重氮化后,与邻氯乙酰乙酰苯胺进行偶合得到偶氮化合物;偶氮化合物再和氯化钴钴化反应得到金属络合染料(兰纳克隆黄S-2G)。本文介绍了该染料的化学结构及合成方法,并检测了染料的应用性能。
The metalline dye Lanacron Yellow S-2G was synthesized by:(1) diazotization of the 2-[[(3-Amino-4-hydroxyphenyl)sulphonyl]amino]benzoic acid followed by coupling with 2'-Chloroacetoacetanilide.(2) metalization with Cobaltous Chloride.This essay introduces molecular structure of the dyestuff' and synthetic route.It's applied properties are examined.
