Process for the production of carbonyl compounds

摘要

In the process for producing a carbonyl compound by contacting olefin and oxygen or oxygen-containing gas with a catalyst in the presence of water, a catalyst comprising a carrier and (a) rhodium, (b) manganese and (c) at least one of the Group IIIA elements (excluding an actinium series elements) is used. Also, the catalyst further containing zinc compounds as the component (d) is used. According to this invention, the selectivity and the conversion of carbonyl compound such as methyl ethyl ketone are highly improved, and halogenated compounds are not produced.
