2,4,6-三(2-羟基-4-丁氧基苯基)-1,3,5-三嗪是一种新型高效紫外线吸收剂。是现有紫外线吸收剂中吸收能力较强和抗氧性能好的品种之一。主要用于农业聚氯乙烯薄膜、工程塑料、乳胶以及清漆涂料等方面。据国外专利记载,先用硝基苯作溶剂,通过付-克反应由三聚氯氰和间苯二酚反应,合成2,4,6-三(2,4-二羟基苯基)-1,3,5-三嗪,然后再与溴代烷反应。在七十年代,我国太原化工研究所、上海东方化工厂、东北师范大学 2,4,6-tris (2-hydroxy-4-butoxyphenyl) -1,3,5-triazine is a new and efficient UV absorber. It is one of the varieties that have strong absorption capacity and good anti-oxidation performance in the existing UV absorbers. Mainly used in agricultural polyvinyl chloride film, engineering plastics, latex and varnish coatings and so on. According to foreign patent records, nitrobenzene is used as a solvent to react 2,4-tris (2,4-dihydroxyphenyl) -1 , 3,5-triazine, and then with brominated alkyl reaction.
