| Abstract: | In this paper, TiSiW12O40/TiO2 catalyst that has not been reported was prapared.Catalyst was characterized by IR and XRD. The catalystic action in synthesizing butyl ester of acetic acid was studied. The optimum condition are: mol ratio of butyl alcohol to acetic acid 1. 20: 1,the quantity of catalyst to feedstock 0. 5% (wt), hydrocarrying anent benzene and reaction time 2. 5 hours. Result show that TiSiW12O40/TiO2 is a very high catalystic activity. |
