Study on synthesis of n-butyl acetate using inorganic salt as catalyst
The catalytic behaviors of FeCl 3·6H 2O, CuCl 2·2H 2O, CuSO 4·5H 2O, CuSO 4, FeSO 4·7H 2O, ZnSO 4·7H 2O in esterification of n butyl alcohol with acetic acid are studied. It is shown that FeCl 3 CuCl 2 has better catalytic properties; in a continuous esterifying-distillating system the catalyst has good stability and activity after 150 hours reacted.
