| Abstract: | Synthesis of dimethyl fumarate (DMF) by esterification of fumaric acid with methanol catalyzed by a ZrO 2/SO = 4 solid superacid catalyst is reported. Effect of catalyst preparation, raw material ratio, reaction time and amount of catalyst used on the yield of DMF has been investigated. At optimal reaction conditions, the yield of DMF reached 90%. Experiments on the repeated use of the catalyst showed that this catalyst is promising for DMF synthesis. |
