| Abstract: | Silicotungstic acid catalyst has been prepared and the n-hexyl acetate is synthesized with silicotungstic as catalyst. The effect of factors on esterification ratio is studied. The result shows that the best reaction conditions are ： based on 0.1 tool acetic acid, molar ratio of n-hexyl alcohol to acetic acid is 1.4, mass of catalyst is 0.3g, the taking water reagent is 15mL, reaction time is 2h. The yield of the product could reach 99.6%. |
