Abstract

A process for the preparation of aldehydes including reacting olefins with carbon monoxide and hydrogen in an aqueous liquid phase in the presence of a rhodium catalyst and a specific class of water soluble aryl phosphines. These phosphines are preferably mixtures of alkali metal salts and quaternary ammonium salts of sulfonated aryl phosphines.
