Abstract

The synthesis of isoamyl hexanoate with isoamyl alcohol and hexanic acid as reactants and solid superacid TiO 2/SO 2- 4 as catalyst has been studied.The influent factors of reaction were investigated.The results show that the appropriate conditions should be:weight of catalyst is 2.0g,molar ratio of isoamyl alcohol to hexanic acid is 1.8∶1,the taking water reagent(Toluene)is 15mL(when hexanic acid is 0.2mol),reaction temperature is 110～140℃,reaction time is 2.0h.The yield of isoamyl hexanoate is about 97.8%.
