摘要
合成了４－氨基－３－甲基偶氮苯－４’－磺酸及４－氨基－３－甲氧基偶氮苯－４’－磺酸，探讨了芳胺做为偶合组分与重氮盐进行重氮偶合反应的方法．研究表明：当在氨基上引入－ＣＨ２ＳＯ３Ｎａ基团时，可保护氨基避免生成重氮氨基化合物，得到氨基偶氮化合物．
Amino 3 methylphenylazo ) benzenesulfonic acid and 4 (4 Amino 3 methoxylpheny lazo) benzenesulfonic acid have been synthesized.The method for aromatic amines (o toluiodine,o-anisidine)to couple with diazonium of p aminobenzenesulfonic acid has been investigated.It is shown that by substituting one H of NH 2 with CH 2SO 3Na the diazoamino compounds can be avoided, and aminophenylazobenzenesulfonic acid can be produced.
