Abstract: PROCESS FOR PRODUCING CATALYST PRECURSORS This invention relates to a novel process for the preparation of rhodium(I) carbonyltriorganophosphorus mono-.beta.-ketoenolate complexes which comprises reacting a halocarbon?bis (triorganophosphorus) rhodium(I) complex, a .beta.-ketoenolate source and an oxygen transfer agent. The complexes so produced are useful as precursors for catalysts in hydroformylation processes. S P E C I F I C A T I O N

Abstract: D-11,271 IMPROVED HYDROFORMYLATION PROCESS A process for the hydroformylation of alpha-olefins employing a rhodium catalyst complexed with carbon monoxide and a triarylphosphine wherein the intrinsic deactivation of the rhodium catalyst which occurs under hydroformylation conditions is inhibited or substantially prevented by determining and correlating the reaction conditions of temperature, carbon monoxide partial pressure and the free triarylphosphine: catalytically-active rhodium metal mole ratio. These conditions can be determined from a mathematical relationship between the combination of these variables and the stability of the rhodium complex catalyst.
