| Abstract: | Sythesis of n - Butyl acetate by esterification of n - buthanol and acetic acid as starting materials in the presence of Phosphomolybdate vanadium heteropolyacid catalyst was proposed. The reaction conditions, such as acid - alcohol ratio, reaction temperature and time, amount of catalysts were examined. The optimum reaction conditions were as follows： the molar ratio of alcohol to acid were 1.2： 1, weight of heteropolyacid was 0.6% of total weight, reaction time was 85min, reaction temperature was 115℃. Under the optimum conditions, the yield was about 93% - 95%. |
