摘　　要：This work presents the formation of butyl levulinate,a potential fuel additive,and an excellent renewable chemical obtained by the butanolysis of furfuryl alcohol(FAL)over a solid acid catalyst.The butanolysis of furfuryl alcohol reaction is a strong function of acidity for which tungstated zirconia(WO_(3)-ZrO_(2)),a robust solid acid catalyst,and a sulfonated carbon catalyst were employed to produce high yields of butyl levulinate targeting a lower initial molar ratio of butanol to FAL.A maximum of 28 mol%yield of butyl levulinate was obtained with tungstated zirconia catalyst.Easily prepared sulfonated carbon catalyst at high reaction temperatures facilitated the complete conversion of reaction intermediate,2-butoxymethylfuran(2-BMF)through which butyl levulinate was formed,and as high as 80 mol%of butyl levulinate yield was produced at an initial mole ratio of 8.5:1 of butanol to FAL.The better results of sulfonated carbon catalyst could be attributed to the presence of-SO3H,carboxylic acid,and phenolic OH groups on the carbon surface.
