Research on the Synthesis Process of Ethylmaltol by Electrochemistry

Ethylmaltol was prepared from ethylfurfuryl alcohol by electrolysis, acidification, glycosidation, oxidation and acidolysis. The ultraviolet spectrophotometric method was used for quantitative determination of ethylmaltol. The chemical structures of the intermediates were characterized by mean of FTIR. The experimental results showed that the yield of ethylmaltol was greatly dependent on electrolyte, quantity of electricity, oxidation time, acidolysis time and acidolysis temperature. The appropriate conditions were electrolyte of NaBr, quantity of electricity of 1.6Ah, oxidation time of 3 hours, acidolysis timeof 3 hours, acidolysis temperature of 100°C and the highest yield of ethylmaltol was 66.76%.
