The preferred wet-proofed catalytic material is activated carbon treated with 0À1 to 100% of its weight of polytetrafluoroethylene, and the preferred homogeneous catalyst is PdCl 2  in HCl. The homogeneous catalyst may include a redox compound. In a modification there are two reaction zones in the first of which said olefinically unsaturated gaseous hydrocarbon is contacted with said aqueous homogeneous catalyst, said redox compound and said solid wet-proofed catalytic material until said redox compound has become substantially deactivated whereupon at least a portion of the resulting reaction mixture is introduced into a second reaction zone and is there, in the presence of said solid wet-proofed catalytic material, treated with an oxidizing gas in order to reactivate said redox compound and the resulting reaction mixture is then recycled to said first reaction zone. Examples prepare methyl ethyl ketone from 1-butene or 2-butene, acetone from propene and acetaldehyde from ethylene. Many other starting material olefins are specified, including butadiene which gives a mixture of crotonaldehyde, acrolein and propionaldehyde.
