Abstract
An improved process for preparing an oxide catalyst comprising vanadium oxide and titanium oxide and silica as an optional component, in which more than 50% of the titanium oxide is in the rutile crystalline form, which comprises calcining a mixture of a vanadium compound and amorphous hydrogel of titanium oxide or a mixture further containing silica, in an oxidizing atmosphere at a temperature of 400.degree. to 600.degree.C.; and a catalyst so obtained. This oxide catalyst is very suitable as a fluidized bed catalyst for prepaing acetic acid by gaseous phase oxidation of butenes.
