Allyl alcohol is hydroformylated with a gaseous mixture of hydrogen and carbon monoxide, in an aromatic hydrocarbon, in the presence of a rhodium complex and a trisubstituted phosphine, to form hydroxybutyraldehydes which are separated from the reaction mixture within an aqueous medium. The carbon monoxide partial pressure, the rate of consumption of carbon monoxide, the rate at which the carbon monoxide is dissolved in the reaction mixture, reaction temperature and the viscosity of the reaction mixture are selected and controlled in an interrelated way to give a high yield of 4-hydroxybutyraldehyde and reduced catalyst consumption.
