摘要：通过重氮化、偶合、还原和烷基化反应合成了７个Ｉ型苯并三唑类紫外线吸收剂，并经红外光谱、质谱、元素分析等手段确证结构，其中６个为新化合物。对所合成的紫外线吸收剂进行了紫外－可见光谱测试，发现所有Ｉ型苯并三唑类紫外线吸收剂皆有优良的紫外吸收能力，摩尔消光系数是Ⅰ型紫外线吸收剂Ｓｅｅｓｏｒｂ７０８的１．５５～１．６８倍。
Seven type II UV absorbers of benzotriazol structure were prepared by diazotization,coupling,reduction and alkylation.Their structures were characterized by IR,MS and elem entary analysis.Six of them were new compounds.The UV V is absorption of those UV absorbers was tested.All those compounds were found to have good absorption ability of UV light,and were found to have 1.55～1.68 times absorption ability of Seesorb 708(type Ⅰ)absorbers.The relation between absorption and molecule structure was also stated.
