苯并三氮唑及其烷基衍生物的合成

Synthesis of Benzotriazole and Its Alkyl Derivatives

以邻硝基氯苯和水合肼为原料,通过缩合、还原反应合成苯并三氮唑,并进一步合成了1,3-二(1H-苯并三氮唑基)丙烷,通过红外光谱对产物结构进行了表征,并对其合成条件进行了优化.

Benzotriazole was synthesized through condensation and reduction reaction with o -nitrochloro benzene, hydrazine hydrate as raw materials. The benzotriazole derivative 1,1 - （ 1,3 - propylene） bis - 1 H - benzotriazole was synthesized and characterized by infrared spectrum. The synthesis conditions were ontimizad
