A study was of the influence of partial replacement of potassium sulfates with sulfates of other alkali metals in the active mass of a vanadium-containing catalyst. Catalyst selectivity for phthalic anhydride increased and optimum operating temperature decreased as the atomic mass of the element added became greater. The composition of the naphthalene oxidation products formed was investigated during progressive replacement of the potassium sulfates in the catalyst by cesium sulfates. Catalysts in which 30 at. % of the potassium was replaced by cesium were found to be most selective with respect to phthalic anhydride.
