A process for the preparation of ketones by carbonylation of alkenes with carbon monoxide, using a catalyst system comprising: component (a) a ruthenium compound, and component (b) at least one acid selected from hydrohalogenic acids and carboxylic acids having a pKa value>/=3 (measured at 25 DEG C. in aqueous solution), with said process being carried out in a water miscible solvent, at a operational pressure in the range of from about 20 bar to about 100 bar and at a temperature in the range of about 70 DEG C. to about 200 DEG C.
