Synthesis of Amyl Butyrate in Liquid-Solid Phase Using β Zeolites as Catalysts

βZeolites were used as catalysts for the esterification reaction of n-butyric acid with n-amyl alcohol in liquid-solid phase. The effects of the amount of the catalyst, and the type of the cation in β zeolite, the ratio of reactants, reaction time, the amount of cyclohexane, and the activation time of the catalyst on the conversion of n-butyric acid and the yield of amyl butyrate were investigated. The kinetic equations for the noncatalytic esterification and those of the esterification with Al-β zeolite as a catalyst were established.
