Study on Catalytic Synthesis of Benzyl Propionate Using Sodium Sulfate Monohydrate

Benzyl propionate was catalytic synthesis by the esterification reaction of benzyl alcohol with propionic acid using sodium sulfate monohydrate The results indicated that NaHSO4·H2O had higher catalytic activity for the reaction The influences of the amount of catalyst used, the molar ratio of benzyl alcohol to propionic acid, reaction time and temperature, and the amount of cyclohexane used on the yield of benzyl propionate have been investigated Under the typical reaction conditions (catalyst/propionic acid is 10 g∶02 mol, benzyl alcohol/propionic acid molar ratio is 01∶02, reaction time is 25 h, reaction temperature is 95~110℃, cyclohexane/ propionic acid is 15 mL∶02 mol), the yield of the ester could reach 823% The catalyst can be easily recovered and reused and has very good activity and stability Sodium sulfate monohydrate as catalyst was better based on the esterification reaction of benzyl propionate with different catalysts
