摘　　要：以对氯邻硝基苯胺和吡啶酮衍生物为原料制得偶氮中间体,并用该中间体还原制备成吡啶酮型苯并三唑紫外线吸收剂UV-M2。采用紫外-可见光光谱、红外光光谱、核磁氢谱、质谱等手段验证了还原产物的分子结构。采用高温高压竭染法,用UV-M2对涤纶织物进行抗紫外整理。结果表明,UV-M2对涤纶有一定的上染能力,可明显改善涤纶的抗紫外性能。Pyridone type benzotriazole UV-absorber UV-M2 is prepared with p-chloro-o-nitroaniline and pyridone derivatives as raw materials to synthesize azo intermediate followed by reduction. Chemical structures of UV-M2 are characterized by UV-vis, FTIR, 1H-NMR and mass spectrometry. UV protection of polyester fabric is carried out with exhaust method. The results show that UV-M2 finish can significantly improve the UV protection property of polyester fabric
