Study on electrochemical synthesis of 2,5-dimethoxy-2,5-dihydrofuranmethanol
Furfuryl alcohol as reactant,NaBr as electrolyte and methanol as solvent,2,5-dimethoxy-2,5-dihydrofuranmethanol,the intermediate of pyromellic acid,was synthesized by electrochemical method.The influence of reaction time,NaBr addition and reaction temperature on the yield was investigated.The results showed that the reaction time and rection temperature had a significant impact on the yield,while the amount of NaBr added had no significant impact on the yield.When furfuryl alcohol 3 g(24 mmol)was added,constant pressure was 15 V,the optimal conditions were reaction time 2.4 h,NaBr addition 1.76 g,reaction temperature-10℃,the average current was 0.93 A,and the yield of 2,5-dimethoxy-2,5-dihydrofuranmethanol is 67.9%.
