Title (EN) IMPROVED METAL-LIGAND COMPLEX CATALYZED PROCESSES
(FR) AMELIORATION DE PROCEDES CATALYSES PAR COMPLEXES METAL/LIGAND
Abstract: front page image
(EN)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 treating said reaction product fluid with an aqueous buffer solution sufficient to neutralize and remove at least some amount of said one or more phosphorus acidic compounds from said reaction product fluid.
(FR)Cette invention se rapporte à un procédé pour séparer un ou plusieurs composés acides de phosphore d'un produit de réaction fluide contenant ce ou ces composés acides de phosphore, un catalyseur à complexe métal/ligand d'organophosphite et éventuellement un ligand d'organophosphite libre, ce procédé consistant à traiter ce produit de réaction fluide avec une solution tampon aqueuse suffisante pour neutraliser et éliminer au moins une certaine quantité du ou des composés acides de phosphore contenu(s) dans ledit produit de réaction fluide.
