The present invention relates to a process for preparing organophosphites, organosphonites and organophosphinites by condensing phosphorus trihalides or organophosphorus halides with organic compounds bearing hydroxyl groups in the presence of polymeric basic ion exchange resins.The process according to the invention makes possible in a simple manner the preparation of trivalent organophosphorus compounds which may serve, for example, as ligands in rhodium complexes which may be used as a catalyst in hydroformylation.
摘要:
Process for separating a dissolved complex catalyst of a metal of group 4, 5, 6, 7, 8, 9 or 10 of the Periodic Table of the Elements and/or any free organophosphorus ligand present from a nonaqueous hydroformylation reaction mixture which contains an aldehyde product and an organic solvent at least one membrane which is more permeable to the hydroformylation product than to the organophosphorus ligand, the separation being carried out under a carbon monoxide partial vapor pressure of more than 200 kPa.
