Title (EN) PROCESSES FOR PRODUCING ORGANOPHOSPHOROUS COMPOUNDS
(FR) PROCÉDÉS DE PRODUCTION DE COMPOSÉS ORGANOPHOSPHORÉS
Abstract:
(EN) The present invention relates to processes for producing organophosporous compositions having low acid content as well as processes for reprocessing partially degraded organophosporous compositions that contain high levels of phosphorous acid. In one embodiment, a process comprises: (a) receiving a solid organophosphite compound that has been recrystallized or triturated, wherein the solid organophosphite compound comprises phosphorous acid; (b) dissolving the solid organophosphite compound in an organic solvent; (c) treating the solution with a weakly basic adsorbent; and (d) collecting the treated organophosphite solution, wherein the acid content of the organophosphite following step (d) is 30 ppm or less.
(FR) La présente invention concerne des procédés de production des compositions organophosporées ayant une faible teneur en acide ainsi que des procédés de retraitement de compositions organophosphorées partiellement dégradées qui contiennent des niveaux élevés d'acide phosphoreux. Dans un mode de réalisation, un procédé comprend : (a) la réception d'un composé organophosphite solide qui a été recristallisé ou trituré, le composé organophosphite solide comprenant de l'acide phosphoreux ; (b) la dissolution du composé organophosphite solide dans un solvant organique ; (c) le traitement de la solution avec un adsorbant faiblement basique ; et (d) la collecte de la solution d'organophosphite traitée, la teneur en acide de l'organophosphite après l'étape (d) étant de 30 ppm ou moins.
