| Abstract: | A phospho molybdic acid catalyst was investigated for the esterification of fumaric acid with methanol in this paper.The influences of raw material ratio,reaction time and amount of catalyst used on the yield of DMF were investigated.The results showed that the optimum conditions should be:Molar ratio of fumaric acid to methanol was 1∶7;weight of catalyst was 4.0g(when fumaric acid was 0.13 mol);the reaction time was 6.0 h.The yield of DMF was more than 85%. |
