Abstract: PROBLEM TO BE SOLVED: To convert an olefinic compound existing in an exhaust gas of hydroformylation carried out by using an aqueous catalyst solution under an economically proper condition into a carbonyl compound. SOLUTION: This hydroformylation for an olefinic unsaturated compound comprises a first reaction stage in which the reaction is carried out in a heterogeneous reaction system by using an aqueous solution containing a rhodium compound containing a water-soluble organic phosphorus (III) compound in the form of complex under 0.4-10MPa to give an exhaust gas. The exhaust gas produced in the first reaction stage is introduced to a second reaction stage, in which the residue of the olefinic unsaturated compound still existing in the exhaust gas is reacted in a heterogeneous reaction system in the presence of the rhodium complex of the organic phosphorus (III) compound as the catalyst under 15-40MPa.

Abstract: Hydroformylation of olefinically unsaturated compounds is carried out as follows. (a) The olefinic compounds are reacted in a heterogeneous reaction system with an aqueous solution containing water-soluble complexes of rhodium compounds and organic phosphorus (III) compounds as catalysts, at 0.4-10 MPa; and (b) the exhaust gas produced is subjected to a second reaction, in which residual olefinically unsaturated compounds still present in the gas are converted in a homogeneous reaction system in the presence of complex compound of Rh with organic P(III) compounds as catalysts at 15-40 MPa.

Abstract: For the recovery of the rhodium contained in them as soluble compounds, the distillation residues of products of the oxo synthesis are treated with oxygen or an oxygen-containing gas in the presence of an alkali metal salt of a C2- to C5-monocarboxylic acid. The noble metal is then extracted from the organic phase using the aqueous solution of a complex-forming reagent, optionally after it has already been previously extracted with water on its own.

Abstract: Waste waters which, in addition to water-soluble inorganic salts, contain water-soluble organic phosphorus compounds, in particular sulphonated arylphosphines and, possibly, other organic impurities, for treatment, first receive an addition of an inorganic acid and are then extracted by a water-insoluble amine. According to a particular embodiment, the inorganic acid is used in the form of a salt of the amine used as extraction medium.

Abstract: Waste gas which is obtained in the hydroformylation of olefinically unsaturated compounds in the presence of an aqueous catalyst solution comprising water-soluble rhodium complexes (1st reaction stage) is fed to a homogeneous reaction system in which residual amounts of the olefinically unsaturated compounds from the first reaction stage are reacted in a homogeneous reaction system (2nd reaction stage).
