| Abstract: | The synthesis of allyl hexanoate with allyl alcohol and hexanic acid as reactants and rare earth solid superacid SO2-4/TiO2/La3+ as catalyst had been studied. The influent actors of reaction were investigated. The results showed that the appropriate conditions should be: weight of catalyst was 0. 8g(weight of hexanic acid if 0. 2 mol) ,molar ratio of allyl alcohol to hexanic acid was 2.0 :1,reaction time was 2. 0 h .the taking water reagent (toluene)was 20 mL. The yield of allyl hexanoate was about 96.2%. |
