Abstract
This patent describes a method of making a catalyst precursor having vanadium and antimony in oxide form in the atomic ratio of Sb to V in the range from 0.8 to 4. It comprises aging in an aqueous solution containing the monoperoxovanadium ion, VO(O{sub 2}){sub +}, until a vanadium-containing sol or gel is formed, and reacting the vanadium while in the aqueous sol or gel form, with an antimony compound which contains Sb having a valence of 3, thereby reducing the average valence of the vanadium to less than 5 and oxidizing antimony to a valence state of 5.
