| Abstract: | Using P-V-Cr heteropoly acid salt as catalyst,methylfuroate was prepared from furfural.The effect of reaction conditions on yield was studied.The results showed the optimum conditions as follows:the ratio of acid to methanol was 4 ∶1,the dosage of catalysts was 5%(α-furancarboxyic acid),and the reaction time was 4 h,the yield can reach 89.5%.It showed that the heteropoly acid salt has good catalytic activity. |
