摘　　要：苯并三唑类紫外线吸收剂是一类重要的光稳定剂，广泛用于各种聚合物材料。本文对水合肼-催化加氢法、水合肼-锌粉法、葡萄糖-锌粉法、硫化钠-锌粉法等二步还原法还原进行了详尽的综述。结果表明：水合肼-催化加氢还原法优于其他方法，该法是绿色无污染的，是适于该类产品工业化的方法之一。Benzotriazole ultraviolet stabilizers were now the most prominent and effective stabilizers widely used in polymeric materials. In this paper, the combination of different reagents （hydrazine hydrate- catalytic hydrogenation; hydrazine hydrate - zinc powders; glucose - zinc powders; sodium sulfide - zinc powders） were reviewed in detail. The results showed that the combination of hydrazine hydrate - catalytic hydrogenation proved to be a better reduction reagent than others, it is green pollution - free , is also one way to industrialization for the products.
