    Abstract: PROCESS FOR PRODUCING MIXTURES OF KETONES AND ALDEHYDES of the Invention A hydrocarbonylation process for producing an aldehyde or a mixture of a ketone and an aldehyde which comprises: (I) forming a reaction mixture comprising: (a) a catalytic amount of a complex catalyst consisting essentially of rhodium in complex combination with: (i) a triorganophosphine, and (ii) a carboxylic acid having a phenyl group substituted at the para position with a non-reactive electron-withdrawing group, said phenyl group being free of further substitution amd said electron withdrawing group being substantially non-reactive in said process; (b) an alpha-olefin having 2 to 5 carbon atoms, (c) carbon monixide, and (d) hydrogen with the proviso that the reaction mixture has mole ratio of said carboxylic acid to rhodium of at least about 2; and (II) maintaining the reaction mixture at a temperature and pressure at which said (b), (c) and (d) react to form an aldehyde or a mixture of an aldehyde and a ketone.

    Abstract: A non-aqueous hydroformylation process for producing aldehydes which comprises reacting an olefinically unsaturated organic compound with carbon monoxide and hydrogen, in a non-aqueous hydroformylation reaction medium containing the olefinically unsaturated organic compound, aldehyde product, solubilized Group VIII transition metal-phosphorus ligand complex catalyst and solubilized free phosphorus ligand, the improvement comprising employing as the phosphorus ligand of said complex catalyst and as said free phosphorus ligand, a monosulfonated tertiary phosphine metal salt of the general formula wherein R represents a radical containing 1 to 30 carbon atoms selected from alkyl, alkaryl, aralkyl and cycloalkyl radicals; M represents an alkali metal or alkaline earth metal cation; and n is 1 or 2 corresponding to the valence of the metal cation.
