| Abstract: | MoO3/SiO2 catalyst was prepared by equivalent-volumetic impregnation method,and was used as catalyst to synthesize n-butyl acetate from acetic acid and butanol.The results showed that the optional reaction conditions were as follows：molar ratio of butanol and acetic acid 4：1,reaction time 3h,catalyst amount 1.0g.The conversion rate of acetic acid could reach 95%,the selectivity of n-butyl acetate was 100%,The catalyst can be reused directly for 5 times. |
