Abstract: Olefinically unsaturated compounds are subjected to hydroformylation to produce the corresponding aldehyde having an additional carbon atom by reacting the compound with hydrogen and carbon monoxide under appropriate conditions of temperature and pressure in the presence of a catalytically active metallo-organic complex in the pores of a solid porous carrier in the form of a solution in a ligand-forming electron-donating phosphorous compound, such as triethyl phosphine, that has a vapor pressure of less than 15 mbar under reaction conditions. The central atom of the metallo-organic complex is preferably rhodium, cobalt, ruthenium or irridium.

Abstract: An improved process for the preparation of a particulate at least inchoately catalytically active composition affixed to the surfaces of a solid particulate carrier material. An aqueous medium is formed by homogeneously suspending a finely divided, solid particulate carrier material in an aqueous solution initially containing (a) a water soluble compound of a metal capable of forming the catalytically active composition which soluble compound, upon increase of the hydroxyl ion concentration in the aqueous medium will form a water insoluble compound, and (b) a hydrolyzable agent which upon heating will develop hydroxyl ions in the aqueous medium. The aqueous solution/suspension thus formed is heated with agitating so as to gradually and homogeneously increase the hydroxyl ion concentration thereby effecting the precipitation of the water insoluble compound on the carrier material. The carrier material, having said insoluble compound deposited thereon, is thereafter separated from the remaining aqueous solution, washed, dried and optionally calcined and/or reduced to form the catalytically active composition. The improvement lies in using as the hydrolyzable agent a compound which will form cyanate ions in the aqueous medium and heating the aqueous medium to a temperature of only between about 20.degree. and 50.degree. C. to hydrolyze the cyanate ions thereby, gradually and homogeneously raising the hydroxyl ion concentration within the aqueous medium.
