摘　　要：本文介绍了活性黄FG染料的合成工艺。以乙酰丁二酸二甲酯、对氨基苯磺酸为原料,经过一系列重氮化、偶合、环合反应得到1-(4’-磺酸苯基)-3-羧基-5-吡唑啉酮钠盐的水溶液,再加入对位酯重氮盐进行偶合反应,直接得到活性黄FG染料。A new synthetic process of reactive yellow FG was introduced in this paper.Dimethyl acetylsuccinate and p-aminobenzene sulfonic acid were used as raw materials to obtain 1-(4’-sulfophenyl)-3-carboxy-5-pyrazoline sodium salt through a series of diazotization,coupling,and cyclization reactions.Then,para-ester diazonium salt was added for coupling reaction to obtain Reactive Yellow FG directly.
