摘要:偶氮苯被广泛用于纺织品和皮革的染色,通过调节环中的取代基,可以获得鲜艳的色彩.在这里,我们报道了在温和条件下,使用过硼酸钠(spb)和催化量的na 2 Moo 4由市售苯胺以高收率制备大量的偶氮苯.冰醋酸是首选的溶剂,苯胺到偶氮苯的转化率是零,相对于spb,Na 2 Moo 4来说,是一阶和一阶和苯胺.根据动力学级数,紫外可见光谱和循环伏安图,提出了转化机理.在20-50oc时约50个苯胺的反应速率及其能量和活化熵分别符合等动力学或exner关系和补偿效应.然而,由迄今为止采用的方法推导的反应速率不能符合哈米特相关性.通过改进的计算获得的分子苯胺的特定反应速率符合哈米特关系.因此,这项工作提出了一种方便,廉价,无害的制备大量偶氮苯的方法,
