Abstract:Taking the synthesis of butyl acetate by the catalytic esteritification of acetic acid and butanol as a probe reaction, a series of studies on the prepation of the catalyst and its activity was made. The conversion ration of butanol and selectivity of butyl acetate are 95% and 100%, respectively, in the optimal condition. Using different analysis method for catalyst, relations with reaction is very good.
