Abstract
This invention provides a catalyst composition suitable for the gas phase oxidation, ammoxidation and oxidative dehydrogenation of olefins to unsaturated aldehydes, unsaturated nitriles and dienes respectively. The catalyst composition comprises, as active catalyst component, a solid solution of Fe, Sb and Ti oxides which has a rutile type crystal structure which is present in the composition in an amount of at least 80 wt. %, and which is represented by the empirical formula Fe.sub.x Sb.sub.y Ti.sub.z O.sub.w, wherein, for x=1, y is in the range of 0.5 to 10, z is in the range of 0.16 to 209 and w represents the number of oxygen atoms corresponding to the oxides of the above elements. The catalyst component is prepared by co-precipitating metal oxides from solutions of corresponding metal salts followed by calcination at 600.degree.-1000.degree. C. of the washed and dried precipitate.
