C. followed by calcining said support at a temperature of about 400.degree. to about 600.degree. C.; and (c) compositing or depositing on said support of step (b), a catalyst precursor salt represented by (ML)(Mo.sub.y W.sub.1-y O.sub.4).sub.a wherein M comprises Cr and/or one or more divalent promoter metals selected from the group consisting of Mn, Fe, Co, Ni, Cu, Zn and mixtures thereof, wherein y is any value ranging from 0 to 1, and wherein L is one or more neutral, nitrogen-containing ligands at least one of which is a chelating polydentate ligand; a=1 when chromium is not one of the promoter metals and 0.5.ltoreq.a.ltoreq.3 when Cr is one of the promoter metals.
