Catalytic Synthesis of Butyl Acetate by Silicotungstic Acid Supported on Activated Carbon |
| |
| Abstract: | The supported silicotungstic acid(SiW/C) catalyst was used to synthesize n butyl acetate with acetic acid and n butyl alcohol. The optimum conditions were determined as follows: acetic acid 0.253 mol,n butyl alcohol 0.22 mol, catalyst 1.5% of the total mass of reactants, temperature 115 ℃ and reaction time 90 min . The conversion of acetic acid was 97.8%,the purity of the product was over 98%.The catalyst could be used repeatedly for many times without distinct loss in activity. |
