C.I.酸性橙116合成工艺的改进

The Improvement on Synthesis of C.I. Acid Orange 116

本文介绍了由间氨基苯磺酸、1-萘胺、对甲基苯酚为原料通过两次重氮化与偶合反应,最后将酚羟基转化为乙氧基,合成出C.I.酸性橙116的方法。对重氮化和偶合反应以及羟基化反应的条件和影响因素进行了研究。

C.I Acid Orange 116 was synthesized from metanilic acid,1-naphthylamine and para-methylphenol by two diazotizations,two coupling reactions and alkoxylation of ethoxyl transformed from phenolic hydroxyl.The conditions and influencing factors of diazotization,coupling reaction and hydroxylation were studied.
