摘要
以２ － 氯－ ４ － 硝基苯胺为原料，先经过重氮化、偶合反应合成出对硝基偶氮苯，经还原后再进行重氮化与偶合反应制备出最终产品分散黄１０４ 。研究了反应条件的影响，在优化条件下，总收率８５ ．７ ％ 。
Disperse 104 was synthesized by a process starting from diazotization of 2-chrolo-4-nitroaniline,followed by coupling,reduction;and then re-diazotization and re-coupling.The factors which influence the reactions were studied on the optimum conditions,the overall yield is 85.7%.
