Patent

CA 2239536

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 ion exchange resin sufficient to remove at least some amount of said one or more phosphorus acidic compounds from said water.

Cette invention concerne un procédé pour séparer un ou plusieurs composés acides du phosphore d'un mélange réactionnel fluide contenant ce ou ces composés acides du phosphore, un catalyseur à complexe métal-ligand organophosphite et éventuellement le ligand organophosphite sous forme libre. Ce procédé consiste à (a) traiter le produit de réaction fluide avec de l'eau en quantité suffisante pour séparer au moins une partie du ou des composés acides du phosphore du mélange réactionnel fluide et (b) à traiter l'eau qui contient les composés acides du phosphore séparés du produit de réaction fluide avec une résine échangeuse d'ions en une quantité suffisante pour extraire de l'eau au moins une partie du ou des composés acides du phosphore.
