    Abstract: The invention relates to phosphabenzene compounds of general formula (I), wherein the radicals R to R , independently of each other, are hydrogen, COOM, SO3M, NR3X, NR2, OR, COOR or SR (with M = hydrogen, NH4 or alkali metal, X = anion, R = hydrogen or C1-6-alkyl), or C1-12-alkyl, C6-12-aryl, C7-12-aralkyl, C7-12-alkaryl or C3-6-heteroaromatics. The alkyl, aryl, alkaryl and aralkyl radicals can be substituted with the aforementioned radicals and two or more of the radicals can be linked to form aliphatic or annellated rings, at least one of the radicals R and R and at least one of the radicals R and R being different from hydrogen. The inventive compounds can be used for producing hydroformylation catalysts.

    Abstract: Extraction of a metal-complex catalyst enriched stream comprises dissolving e.g. reaction products and by-products, in a reaction medium by an agent containing phosphorous and/or nitrogen atoms, modified organic metal complex catalyst; distillating the catalyst free stream of the reaction discharge; separating high boiling and non-distilled components of the reaction discharge and the sump product of the distillation into a permeate- and retentate- stream and recycling the retentate stream enriched, completely or partially into the metal-complex-catalyst. Extraction of a metal-complex catalyst enriched streams, obtained from the liquid discharge of a metal complex catalyst reaction comprises dissolving reaction products, by-products, non-converted educt, solvent, homogeneous or colloid in a reaction medium by an agent containing one or more phosphorous and/or nitrogen atoms, modified organic metal complex catalyst with a molecular weight of greater than 200 D and free ligands; distillating the catalyst free stream containing low boiling components of the reaction discharge at atmospheric pressure or low pressure; separating high boiling and non-distilled components of the reaction discharge and the sump product of the distillation into a permeate- and retentate- stream, by a membrane-separator device and recycling the retentate stream enriched with the metal-complex catalyst, completely or partially into the metal-complex-catalyst.
