  Provided is a process for preparing 2H-benzotriazole UV absorbers containing a perfluoroalkyl moiety at the 5-position of the benzo ring, for example a trifluoromethyl group, which involves diazotizing the perfluoroalkyl substituted o-nitroaniline using concentrated sulfuric acid plus sodium nitrite or nitrosylsulfuric acid to form the corresponding monoazobenzene intermediate via the diazonium salt intermediate which is reduced to the corresponding 5-perfluoroalkyl substituted 2H-benzotriazole UV absorber compound by conventional reduction means. Also provided is a novel one-pot, multiphase reaction for the preparation of 2(2-nitrophenylazo) substituted phenols, which are precursors for 2H-benzotriazole UV absorbers.

  提供了一种制备在苯环的5位含有全氟烷基基团（例如三氟甲基基团）的2H-苯并三唑紫外吸收剂的方法，该方法涉及使用浓硫酸加硝酸钠或亚硝基硫酸制备全氟烷基取代的邻硝基苯胺，以形成相应的单氮偶联苯中间体，通过传统还原手段将二氮盐中间体还原为相应的5-全氟烷基取代的2H-苯并三唑紫外吸收剂化合物。还提供了一种用于制备2(2-硝基苯基偶氮)取代酚的新型一锅多相反应，这些化合物是2H-苯并三唑紫外吸收剂的前体。

  2-[2-Hydroxy-3,5-di-tert-octylphenyl]-2H-benzotriazole exhibits outstanding efficacy in protecting organic substrates from light induced deterioration as well as good resistance to loss by volatilization or exudation during the high temperature processing of stabilized compositions. This stabilizer and its 5-chloro analog exhibit great resistance to volatilization, enhanced solubility in selected solvents, desirable absorption characteristics in the ultraviolet range and photographic inertness. This combination of properties makes these benzotriazoles particularly useful in photographic compositions especially in protecting color dye images against the harmful effects of ultraviolet light.

  2-[2-羟基-3,5-二叔丁基苯基]-2H-苯并三唑表现出在保护有机基质免受光诱导劣化方面的杰出功效，以及在稳定组分的高温加工过程中具有良好的抗挥发或渗出性能。这种稳定剂及其5-氯代衍生物具有极强的抗挥发性，增强了在选定溶剂中的溶解性，在紫外光范围内具有理想的吸收特性和摄影惰性。这些性质的结合使得这些苯并三唑在摄影组合物中特别有用，尤其是在保护彩色染料图像免受紫外光的有害影响方面。
