Study on the Technological Conditions of CZ Type Solid Acid Catalyst on Synthesis of Butyl Acetate

CZ type solid acid catalyst was prepared by immersion method in the synthesis of butyl acetate and its catalytic action in the synthesis of butyl acetate from acetic acid and n-butyl alcohol was studied in this study. Results indicated temperature, mol ratio of n-butyl alcohol and acetic acid, reaction time could impact on the catalysis property. The suitable craft response condition is that temperature is 130~150 ℃, mole of ratio of n-butyl alcohol and acetic acid is 1.1~1.2, reaction time is 4~5 h.
