摘要: A silica-supported peroxycarboxylic acid oxidant, 2-percarboxyethyl silica (SiO2@(CH2)2COOOH), was successfully prepared and used for the epoxidation of fatty methyl esters (FAMEs) vegetable oils. Among oxidants under different conditions, C-SiO2@(CH2)2COOOH (TEOS:CTES = 2:1) had highest surface area, pore volume, peroxide value. It also exhibited activity reactions. For linoleate, 92.76% yield epoxidized product obtained at room temperature. Other unsaturated FAMEs with 1 3 double bonds were efficiently converted to their epoxides. Moreover, oxidant applied oils, olive oil, linseed oil high Finally, regenerated through a simple oxidation process H2O2 recycled least 5 times without much drop in reactivity.
