摘　　要：以三聚氯氰(TCT),浓硫酸,对-β-羟基乙砜苯胺硫酸酯和2,4-二羟基二苯甲酮(UV-0)为原料,经三步反应合成一种具有双活性基团的水溶性紫外吸收剂2-{4-[4-(4-苯甲酰基-5-羟基-2-磺酰苯氧基)-6-氯-1,3,5-三嗪-2-酰氨基]苯磺酰基}乙基磺酸钠(UV-SHTES),产物的结构分别用FT IR、NMR、MS、SEMEDS表征。并对反应中各项条件对反应产率的影响进行了探讨。UV-SHTES的最佳合成工艺条件为:n(2,4-二羟基-5-磺酸基二苯甲酮)∶n(双活性基)∶n(Na_2CO_3)=1.1∶1∶1,在水中40℃下反应2h,产率71%。UV-SHTES的紫外吸收性能在240～320nm内表现良好,酸碱稳定性较好,水溶性得到大幅改善。A reactive water-soluble UV-absorber, sodium 2-{4-[4-（4-benzoyl-5-hydroxy-2-sulfonatophenoxy）-6-chloro-1,3,5-triazin-2-ylamino]phenylsulfonyl}ethyl sulfate（UV-SHTES）was synthesized by using 2,4-dihydroxy benzophenone（UV-0）,concentrated sulfuric acid,sulfuric acidmono-[2-（4-amino-benzenesulfonyl）-ethyl]ester and 2,4,6-trichloro-1,3,5-triazine（TCT）as starting materials.The chemical structure was confirmed by FT IR,NMR,MS and SEM-EDS.The effects of various conditions on the reaction yield were discussed.The highest yield（71%）of UV-SHTES can be obtained by using the feeding of n（TCT）∶n（sulfuric acid sodium salt mono{2-[4-（4,6-dichloro-[1,3,5]triazin-2-ylamino）-benzenesulfony]ethyl}ethyl）∶n（Na2CO3）=1.1∶1∶1 at 40 ℃for 2 hin aqueous media.UV absorption of UV-SHTES is good at 240～320 nm with a good acid-base stability and an improved water solubility.
