Study on the Synthesis Conditions of Octyl Acetate Under Ultrasonic

Octyl acetate was synthesized from acetic acid and n-octanol using sodium bisulfate as catalyst without solvent under ultrasonic.The optimal reaction conditions were as follows:mole ratio of n-octanol to acetic acid of 1∶2.0,1.0% catalyst based on the total mass of the reactants,reaction time of 20min and reaction temperature of 84℃.Under these conditions,the yield of octyl acetate is up to 80.1%.The catalyst could be repeatedly used.
