摘　　要：苯并三唑类衍生物是一类重要的紫外线吸收剂，由邻硝基偶氮苯催化加氢制备苯并三唑类紫外线吸收剂合成路线具有工艺简单、产品质量高、环境污染小等优点，展现出良好的发展前景。本文就该领域的研究进展进行了综述，并对其技术发展作了展望。Benzotriazole derivatives is a commercially important uhraviolet absorbers. Among the preparation routes of catalytic hy- drogenation of o - nitroazobenzene to benzotriazole ultraviolet absorbers has some remarkable advantages, such as simple synthesis process, high - quality products and friendliness to environment, therefore this process has a good prospect. This paper reviews the recent re- search progress and its developmental trend is also discussed.
