A method for synthesizing benzotriazole comprises acts of: preparing a first solvent comprising 2-(2-hydroxy-5-methylphenyl) benzotriazole, a basic agent and molecular sieves and a second solvent comprising 3-chloro-2-alkyl propylene; mixing the solvents; and heating the solvents. This method requires only one reaction vessel and produces few by-products, therefore is simpler and cheaper to produce. Furthermore, the molecular sieves are cheaper than catalysts in conventional reactions and may be recycled, giving even greater economic benefits.
一种合成苯并三唑的方法包括以下步骤:准备第一溶剂,其中包括2-(2-羟基-5-甲基苯基)苯并三唑、碱性剂和分子筛,以及第二溶剂,其中包括3-氯-2-烷基丙烯;混合这些溶剂;并加热这些溶剂。该方法仅需要一个反应容器并产生少量副产物,因此更简单、更便宜。此外,分子筛比传统反应中的催化剂更便宜,可以回收利用,从而带来更大的经济效益。
