摘要
以4,4′-二氨基苯磺酰替苯胺(DASA)、1,8-二氨基萘为原料,通过重氮化、偶合反应合成了一种新型可降解绿色环保型偶氮染料—4,4′-二(4,5-二氨基-1-偶氮萘)苯磺酰替苯胺,产品结构经MS、^(1)H NMR和元素分析进行了表征。对反应条件进行了优化,当反应时间45 min、温度0~5℃及pH为6时,产率可达57.3%。
A novel environmental friendly and degradable azo dye,4,4′-bis(4,5-diamino-1-azonafthalene)benzene sulfonylidene was synthesized,using 4,4′-diaminobenzene sulfonylidene(DASA)and 1,8-diaminaphthalene as raw materials,through diazotization reaction and coupling reaction.The target product was characterized by MS,^(1)H NMR and elemental analysis.The highest yield reached 57.3%under the reaction time of 45 min,reaction temperature between 0~5℃and pH value equal to 6.
