Abstract

Carbonyl compounds can be prepared by catalytic oxidation of olefins with oxygen or oxygen-containing gases in a microemulsion (ME) as reaction medium and catalyst support. The catalysts present in ME and used for this purpose are characterized by a content of 0.0001-10% by weight of a Pd compound and by a content of 0.0005-20% by weight of a subgroup metal compound or a quinone, based on the total weight of the catalysts present in the ME.
