Preparation of Catalyst SO_4~(2-)/ZrO_2SiO_2 and Its Catalysis for Esterification of Acetic Acid with Butanol

おhe title catalyst is prepared by treating the binary oxide ZrO_2SiO_2 with 0.5 to 1.0 mol/L sulfuric acid solution. This binary oxide is made from normal reagents which contain zirconium and silicon. The catalysis of this catalyst for the esterification of acetic acid with butanol is investigated. It is shown that the catalyst is five to ten times more active than the catalyst SO_4~(2-)/ZrO2. The result of indicator test shows that the acidic strength of the catalyst is less than -12.14(H0). The effect of some preparation conditions on the activity of catalyst is also studied in this paper.
