| LU Yan-ping; LI Lin-sheng （Shanxi University of Science & Technology; Xianyang 712081; China） |
| Abstract：Glycidyl methacrylate was synthesized by reaction of methylacrylic acid and epichorohydrin in the present of quatemary ammonium salt as catalyst and 1,4- dihudroxy-benzene as polymerization inhibitor. The optimum reaction conditions were obtained as follow:reaction time 4h, reaction temperature 110℃,the amount of triethbenzylammonium chloride 0.5%(mol).The yield is 80.6 %,and the purity is 98%. |
| Key words：glycidyl methacrylate; the phase transfer catalyst; synthesis; purification |
