Abstract

A process for the hydroformylation of aldehydes comprising reacting aliphatic olefins with carbon monoxide and hydrogen in a liquid phase in the presence of water, a rhodium catalyst and a water soluble salt of a sulfonated or carboxylated triarylphosphine, the reaction taking place in the presence of an aqueous phase having a pH of about 5.5 to about 6.2.
