Synthesis of n-hexyl Acetate Catalyzed by Phosphotungstic Acid

n-hexyl acetate was synthesized from acetic acid and hexyl alcohol with phosphotungstic acid as catalyst.The effect of factors on esterification ratio was studied.The result shows that the best reaction condition was: based on 0.1 mol acetic acid,molar ratio of n-hexyl alcohol to acetic acid was 1.4, mass of catalyst was 0.3 g,the taking water reagent was 15 mL,reaction temperature was between 110 and 130,reaction time was 30 min.The yield of the product could reach 99.6%.
