摘　　要：4-羟基偶氮苯是一种重要的合成中间体,广泛的用于偶氮苯衍生物的合成及科学研究。本文通过重氮偶合反应制得4-羟基偶氮苯,经红外光谱和熔点分析鉴定了结构,研究了配比、温度、溶液pH值、反应时间等反应条件对目的产物收率的影响,得到最佳反应条件。4-hydroxyazobenzene is an important synthetic intermediate, which can be applied extensively in the synthesis of azobenzene derivant and scientific research. In this paper, 4-hydroxyazobenzene was prepared by azo coupling reaction, the structure of which was confirmed through infrared spectrum and melting point analysis, and the optimal reaction condition was resolved, such as the ratio, temperature, pH, and time.
