Abstract of Disclosure A process for the preparation of a rhodium catalyst comprising dissolving a carboxylic acid salt of rhodium in a solvent taken from the class consisting of aliphatic, cycloaliphatic, aromatic hydrocarbons and mixtures thereof. The carboxylic acid has 2 to 18 carbon atoms. This salt is reacted with carbon monoxide and hydrogen to form a rhodium hydridrocarbonyl which is reacted with an aqueous solution of a triaryl phosphine. The aqueous solution may be present during the initial reaction of the rhodium salt or may be added thereafter. A catalyst which is the product of the foregoing process is also disclosed, as is a method of producing aldehydes using the catalyst.
