Process for recovery of phosphine oxides and alklylsarylphosphines from reaction mixtures of a homogeneous hydroformylation |
| abstract |
A process for separating off phosphine oxides and alkylarylphosphines from an organic reaction mixture of a homogeneous hydroformylation carried out with the use of a catalyst system, which reaction mixture contains organometallic complex compounds and, in a molar excess, ammonium salts of aromatic phosphines as ligands comprising subjecting the organic reaction mixture to an extraction treatment with a 0.001-0.5% strength by weight of an alkali metal hydroxide or alkaline earth metal hydroxide solution and separating off the aqueous phase containing the phosphine oxides and alkylarylphosphines to decrease markedly the concentration of the phosphine oxides and alkylarylphosphines in the hydroformylation mixture, which process is particularly suitable for continuously operated hydroformylations. |
