PURPOSE: To easily, stably obtain in high yield a carbonyl compound useful as a solvent or chemical feedstock by reacting an olefin with an oxidative gas under specified conditions.
CONSTITUTION: An olefin is reacted with an oxidative gas in the presence of a palladium compound (e.g. PdSO4.2H2O), polyoxoanionic compound [e.g. (PV3Mo9O40)6-] and iron-contg. compound [e.g. Fe2(SO4)3] in a solvent consisting of at least one kind of compound selected from oxygen-contg. compounds (e.g. 1,4-dioxane) and sulfur-contg. compounds (e.g. dimethylsulfoxide) or a mixed solvent compound of the compound (s) and water to obtain the objective carbonyl compound useful as a solve or chemical feedstock such as methyl ethyl ketone, methyl isobutyl ketone, acetone, cyclopentanone or cyclohexanone, or as a precursor for higher alcohols such as a ketone or aldehyde. For this reaction, catalytic activity deterioration can be prevented and reaction rate can be maintained stably at high levels without the need for separating reaction process from catalyst regeneration process.
