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 . 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.
