摘要
研究了以磷钨杂多酸为催化剂,以马来酸酐和甲醇为原料合成富马酸二甲酯.反应的最佳条件是:马来酸酐和甲醇的物质的量比为1∶6,催化剂用量为马来酸酐质量的8%,反应时间6h,产率达91.7%.
Synthesizing method of dimethyl fumarate from methane alcohol and maleic anhydride by phosphotungstic acid was studied . The optimum conditions were as follows： the molar ratio of maleic anhydride to methane alcohol was 1：6, the mass of phosphotungstic acid was 8% of maleic anhydride, the reaction time was 6h. The yield of product can reach 91.7%.
