This invention relates to a process for separating one or more phosphorus acidic compounds from a reaction product fluid containing said one or more phosphorus acidic compounds, a metal-organophosphite ligand complex catalyst and optionally free organophosphite ligand which process comprises (a) treating said reaction product fluid with water sufficient to remove at least some amount of said one or more phosphorus acidic compounds from said reaction product fluid and (b) treating the water which contains phosphorus acidic compounds removed from said reaction product fluid with an acid removal substance sufficient to remove at least some amount of said one or more phosphorus acidic compounds from said water.

Procédé de séparation d'un ou de plusieurs composés acides de phosphore dans un fluide produit par une réaction, contenant ce ou ces composés acides de phosphore, un catalyseur constitué d'un complexe métal-ligand organophosphite et d'un ligand organophosphite éventuellement libre, consistant à a) traiter ce fluide produit par une réaction avec de l'eau en quantité suffisante pour éliminer au moins une certaine quantité de ce ou de ces composés acides de phosphore de ce fluide produit par une réaction et b) traiter l'eau contenant les composés acides de phosphore éliminés du fluide produit par une réaction à l'aide d'une substance d'élimination des acides en quantité suffisante pour éliminer au moins une certaine quantité de ce ou de ces composés acides de phosphore de cette eau.
