Synthesis of n-butyl acetate catalyzed by aluminum chloride crystal

A method of synthesizing nbutyl acetate catalyzed by aluminum chloride crystal(AlCl3·6H2O) has been studied.AlCl3·6H2O is found as a catalyst nonpolluting and highactive.The optimum reaction conditions are as follows:molar ratio of acetic acid to nbutanol is 0.7,the catalyst is 0.6 g,the reaction time is 2.0 h,the yield of nbutyl acetate is about 98.6% when acetic acid is 0.2 mol.The reuse of the catalyst is investigated.
