标 题 :Process for the separation and recovery of rhodium from the products of the oxo synthesis
发明人：LAPPE PETER; BEXTEN LUDGER; KUPIES DIETER
权利人:HOECHST AG
摘要:To separate and recover rhodium, the distillation residues of oxo synthesis products are initially treated with an oxidant. Then the reaction mixture is reacted, in the presence of carbon monoxide (or a compound which splits off carbon monoxide), with an aqueous solution of a reagent forming a water-soluble complex compound with rhodium. The reaction mixture breaks into an organic phase and an aqueous phase, the complex goes to the aqueous phase as it is substantially insoluble in the organic phase.

标题 :Process for recovering rhodium from oxo synthesis reaction products
摘要:1. A process for separating and recovering rhodium used as a catalyst without a complexing agent by extraction from an organic solution of the products of the Oxo synthesis with an aqueous solution of organic phosphines having the general formula see diagramm : EP0156253,P10,F2 as complexing reagents, where Ar**1 , Ar**2 and Ar**3 each denote a phenyl or naphthyl group, Y**1 , Y**2 and Y**3 each stand for a straight-chain or branched alkyl group having 1 to 4 carbon atoms, an alkoxy group, a halogen atom, the OH, CN, NO2 - or R**1 R**2 N group, R**1 and R**2 each standing for a straight-chain or branched alkyl group having 1 to 4 carbon atoms, X**1 , X**2 and X**3 are each a sulfonate (SO3 **- ) and/or a carboxylate (COO**- ) radical, m1 , m2 and m3 are the same or different integers from 1 to 3 and at least one number m1 , m2 or m3 is equal to or greater than 1, n1 , n2 and n3 are the same or different integers from 0 to 5 and alkali metal, alkaline earth metal, zinc, ammonium or quaternary ammonium ions of the general formula N(R**3 R**4 R**5 R**6 )**+ , R**3 , R**4 , R**5 , R**6 each denoting a straight-chain or branched alkyl group having 1 to 4 carbon atoms are contained in the sulfonates and carboxylates, characterised in that a solubiliser is added to the aqueous solution of the complexing agent.

摘要:For the preparation of predominantly unbranched higher primary alcohols, olefins from the Fischer-Tropsch synthesis are reacted with hydrogen and carbon monoxide in the presence of water and a catalyst which is rhodium, in metallic form or as a compound, and a water-soluble phosphine. The reaction product obtained is hydrogenated. The water-soluble phosphines employed are compounds whose anion is a phosphine containing at least one sulfonated or carboxylated aromatic radical and whose cation is a quaternary ammonium or phosphonium ion.

摘要:The invention relates to a hydroformylation method, whereby the homogeneous liquid reactor discharge is first supplied to a gas/liquid separator and then run through an extraction column with a counter-current of synthesis gas and finally fed to an evaporator. The invention is characterised in that the homogeneous liquid mass flow is supplied to the upper section of the extraction column at a temperature above 90° C.
