摘要

The process comprises the vapor phase oxidation of lower molecular weight olefins to the corresponding unsaturated aldehydes and unsaturated carboxylic acids in the presence of a catalyst comprising the oxides of iron, bismuth, molybdenum and at least one element of the Group II elements as essential components, and optionally the oxides of phosphorus, arsenic and an alkali metal.
