| Abstract: | A new inorganic compound solid super acid SO 2- 4/TiO 2 ZrO 2 catalyst was prepared and measured.The effect of calcination temperature on the catalytic activity of the catalyst was investigated by synthesis dimethyl fumarate(DMF) via esterification of fumaric acid with methanol.The optimum reaction condition determined by orthogonal experiment was fumaric acid∶methanol=1∶6(molar ratio),weight of the catalyst= 2.0% (based on the weight of fumaric acid and methanol),the calcination temperature=550 ℃,reaction time 6 h. The yield of DMF is above 91.2%. |
