    Abstract: O.Z. 0050/033918 of the disclosure: A process for the preparation of butanedicarboxylic acid esters, whereina) an aqueous cobalt salt solution is treated, at from 50 to 200.degree.C and under a pressure of from 50 to 500 bar, with excess carbon monoxide and hydrogen in the presence of active charcoal which has been laden with cobalt carbonyl,b) the resulting aqueous solution of cobalt carbonyl hydride is extracted with butadiene or a butadienecontaining hydrocarbon mixture and the aqueous phase is separated off,c) the butadiene, or butadiene/hydrocarbon mixture, containing cobalt carbonyl hydride, cobalt carbonyl and butenyl-cobalt tricarbonyl, is reacted with carbon monoxide and excess C1-C4-alkanol in the presence of from 0.5 to 2 moles, per mole of butadiene, of a tertiary nitrogen base having a pKa of from 3 to 11, at from 80 to 150.degree.C under a pressure of from 300 to 2,000 bar,d) the resulting reaction mixture is freed from the tertiary nitrogen base contained therein, down to a content of from 0 1 to 0.3 mole per mole of pentenoic acid ester, and from excess hydrocarbons, and the pentenoic acid ester remaining in the reaction mixture is reacted with carbon monoxide and excess C1-C4-alkanol at from 140 to 200.degree.C and under a pressure of from 100 to 400 bar in the presence of the amounts of cobalt carbonyl and tertiary nitrogen base contained in the reaction mixture, O.Z. 0050/033918e) the reaction mixture containing cobalt catalyst, butanedicarboxylic acid esters, alkanols, tertiary nitrogen base, pentenoic acid esters and by-products is treated with an oxidizing agent in the presence of the aqueous acid solution which has been separated off in stage b), and the mixture is separated into an organic phase, from which butanedicarboxylic acid esters are isolated by distillation, and an aqueous phase, andf) the aqueous phase is extracted with C1-C4-alkyl esters of C1-C5-alkanecarboxylic acids and/or alkenecarboxylic acids, the phases are separated, and the aqueous phase thus obtained is freed from alkanols and tertiary nitrogen base by distilling these off and is recycled to stage a).

    Abstract: The isolation and regeneration of catalysts of type I or II ClRh(CO)(PR3)2 I Hrh(CO)(PR3)3 II, where the R's are identical or different hydrocarbon radicals, to give the catalysts in a pure form, is effected by regenerating aqueous rhodium salt solutions, as obtained on treating distillation residues of hydroformylation mixtures with oxygencontaining mineral acids and peroxides, by a method wherein the aqueous rhodium salt solutions are treated with a cation exchanger, the latter is then separated from the solution, the absorbed rhodium ions are desorbed with hydrochloric acid, the hexachlororhodate solutions, containing hydrochloric acid, are reacted, in the presence of a water-soluble organic solvent and a tertiary phosphine PR3, with carbon monoxide, or with compounds which eliminate carbon monoxide, at from 0 to 150.degree.C and from 1 to 5 bars, to form the chloro- complexes I which are either separated off or converted to the hydrido-complexes II using under hydrogenating conditions hydrogen or hydride ions, and the resulting complexes II are separated off.
