    Abstract: Hydridocarbonyltris(triorganophosphorous)rhodium compd. is prepd. for use as hydroformylation agent. Condenced rhodium complex soln., hydrogen gas, alcohol diluent, carbon monoxide and triorganophosphorous ligand are mixed to give homogeneous organic reaction soln.. This nonaqueous reaction soln. is reacted at 20-120≦̸C to give hydridocarbonyltris(triorganophosphrous) rhodium compd.. The solvent of condensed rhodium complex soln. is perhydroformylation reaction medium. This process is simple and economical.

    Abstract: Aldehydes are produced by hydroformylating an olefinically unsatd. compd. with CO and H2 in a reaction medium contg. a rhodium complex catalyst, free triarylphosphine ligand and free organic tert. bisphosphine monoxide ligand of formula(I) with the mole ration of triarylphosphine ligand to (I) being (2-30):1 (Ar is an opt. substd. aryl; R1, R2 and R3 are opt. subst. monovalent hydrocarbyl; and Y is a divalent bridging gp.). Also clamined is a rhodium complex hydroformylating catalystic precursor compsn. comprising a solubilised rhodium carbonyl phosphorus acetylacetonate complex, an organic solvent and the ligands given above.

    Abstract: PROCESS FOR REMOVING HYDROPEROXIDES AND ALDEHYDES FROM ALLYL-ALKYL ETHER Described herein is a process for the conversion of hydroperoxides, present in allyl-alkyl ethers to products including .alpha.,.beta.-unsaturated aldehydes and for reducing such .alpha.,.beta.-unsaturated aldehydes to alcohols prior to the use of the ether as a feedstock in a hydroformylation reaction to produce the corresponding ether aldehyde. The process involves contacting the ether with a metal hydride, either in aqueous solution and/or by means of an ion exchange resin. Such treatment decomposes the hydroperoxides and then reduces their .alpha.,.beta.unsaturated aldehyde decomposition products, thereby reducing the catalyst inhibition period present in the hydroformylation reaction which is observed when such .alpha.,.beta.-unsaturated aldehyde impurities are present.
