| Abstract: | Butyl isovalerate was synthesized by using modified strong acid cation ion exchange resin by cerium sulfate as the catalyst.Factors influencing the yield were discussed and the best conditions were found.Experimental result showed that when the amount of isovaleric acid was 0.2 mol,molar ratio of alcohol to acid was 1.6,the mount of catalyst was 2.0 g and reaction time was 60 min,the amount of benzene was 5 mL,the yield was 91.3%. |
