Catalytic synthesis of n-butyl acetate catalyzed by MoO_3/SiO_2

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.
