A process for the hydroformylation of a compound of general formula, , R1 - CH = wherein R1 represents a hydrogen atom or an alkyl group having from 1 to 6 carbon atoms and R2 represents an alkyl group having from 1 to 18 carbon atoms, which comprises hydroformylating the compound of general formula I with carbon monoxide and hydrogen in the liquid phase in the presence of a homogeneous catalyst system comprising, a) a rhodium compound and b) one or more triphenylphosphites, the phenyl groups of which may optionally be substituted by halogen, alkyl having from 1 to 6 carbon atoms, alkoxy having from 1 to 6 carbon atoms, carboxy or cyano, at a temperature in the range of from 50 to 100°C and a pressure in the range of from 3 to below 100 bars.
