摘要
本文简要叙述由间二氨基苯磺酸、苯胺等为原料分别与三聚氯氰缩合 ,缩合物经重氮后与邻氯苯基吡唑酮偶合合成染料中性亮黄 3GL的工艺过程。
A process for the synthesis of the neutral brilliant yellow dyestuff was firstly carried out with m-diaminobenzenesulfonic acid, aniline, and then condensed with cyanuric chloride. Then the condensation product undergoes the diazotozation with 3-methyl-1-(2-chloro-nyl)-5-pyrazolone coupling to synthesise Neutral Brilliant Yellow 3GL.
