Abstract
Ethyl furoate is a type of new perfume which has been ratified to use in the United States,Japan and some other countries.Furoic acid was synthesized with distilled furfural by Cannizzaro reaction,and studying the factors affecting the purity of furoic acid.Ethyl furoate was synthesized by using furoic acid and ethanol as the materials and sodium acid sulfate as catalyst.Sodium acid sulfate is a kind of cheap,easily obtainable and reusable inorganic crystal scintillator with weak corrosiveness and no pollution.The effects of furoic acid on conversion were studied by orthogonal experiments.The results showed that the main factors affecting the result were the ratio of acid and ethanol and reaction time;the secondary factor was the weight of catalyst,and the most appropriate condition should be:The ratio of acid and ethanol was 1 ∶5,the reaction time was 4 hours and the dosage of catalyst was 0.15g(based on 0.1mol furoic acid).The conversion of furoic acid is 84.4%.
