摘　　要：以间氨基苯酚、间苯二胺为原料,通过重氮化-偶合反应合成偶氮化合物3'-羟基-间二氨基偶氮苯(化合物1)。分析了反应时间、pH值、化学计量比、温度和溶剂等因素对合成的影响,化合物1的合成为偶氮化合物提供新实例。进一步通过紫外光谱对1的光谱性质进行了研究,其具有较大的摩尔吸光系数和良好的酸碱变色性。此外,我们还考察了有机溶剂对化合物1紫外光谱的影响。Azo compound 3'-hydroxy-m-diaminoazobenzene(compound 1)was synthesized from m-aminophenol and m-phenylenediamine by diazotization-coupling reaction.The effects of reaction conditions such as reaction time,pH value,stoichiometric ratio,temperature and solvent on the synthesis were analyzed.The synthesis of 1 provides a new example for azo compounds.Compound 1 has a large molar absorptivityand good acid-base discoloration.In addition,the effects of organic solvents on the ultraviolet spectra of compound 1 were also investigated.
