The present invention is for a process for making a catalyst for production of unsaturated aldehydes, such as methacrolein, by gas phase catalytic oxidation of olefins, such as isobutylene, said catalyst containing oxides of molybdenum, bismuth, iron, cesium, tungsten, cobalt, nickel, antimony, magnesium and zinc. The process is a two-part synthesis of the catalyst with the water insoluble components in one part and the water soluble components in the other part. The water insoluble components are co-precipitated to form an intermediate catalyst precursor of a precipitated support incorporating oxides of the metal components. The intermediate catalyst precursor is filtered and washed to remove nitrates. The intermediate catalyst precursor is slurried with the remaining water soluble components. A final catalyst precursor is formed by removing the water and incorporating the water soluble components. This two-part process reduces the amount of nitrates in the final catalyst precursor.
