摘要： The invention relates to a hydroformylation process comprising the steps of: (a) contacting one or more ethylenically unsaturated compound(s) in a reaction zone with carbon monoxide and hydrogen gas in the presence of a solvent and a homogeneous catalyst based on a Group 8, 9 or 10 metal, and a non-ionically charged phosphorus ligand to form a crude hydroformylation product; (b) allowing a major portion of the solvent, wherein a major portion of the catalyst is dissolved, to separate and be withdrawn from the crude hydroformylation product in a phase separation zone; (c) removing from the separated hydroformylation product emerging from step (b) substantially all remaining catalyst dissolved therein with a non-aqueous extractant in an extraction zone.

摘要： A process for the hydroformylation of ethylenically unsaturated compounds with carbon monoxide and hydrogen in the presence of a catalyst system comprising:a) a source of palladium, platinum, or nickel cations;b) a source of anions, other than halide anions, such as unsubstituted alkyl sulfonic acids, aryl sulfonic acids, perfluorinated alkyl sulfonic acids, perfluorinated aryl sulfonic acids, boric acid derivatives or alkylated versions thereof;c) a source of at least one bidentate ligands of the formulaR.sup.1 R.sup.2 M.sup.1 RM.sup.2 R.sup.3 R.sup.4 (I)wherein M.sup.1 and M.sup.2 independently represent a phosphorus, arsenic or antimony atom, R represents a bivalent bridging group containing from 1-4 atoms in the bridge, R.sup.1 and R.sup.2 together represent a bivalent cyclic group whereby the two.cndot.free valencies are linked to M.sup.1, and R.sup.3 and R.sup.4 independently represent a hydrocarbyl group, or together represent a bivalent cyclic group whereby the two free valencies are linked to M.sup.2 ;wherein said source of cations, anions, and ligands are selected to form a catalyst system having a solubility of at least 2.times.10.sup.-4 mole of the cation a) per liter of a liquid mixture comprising said ethylenically unsaturated compound and the hydroformylation products;and separating the hydroformylation products from the catalyst system in a solventless evaporative separator such as a falling film evaporator or a wiping film evaporator.
