Patent

CA 2234606

Accordingly, a process is provided for the hydroformylation of ethylenically unsaturated compounds having at least 4 carbon atoms by reaction thereof with carbon monoxide and hydrogen in the presence of a solvent and a catalyst system obtainable by combining: a) a source of Group VIII metal cations; b) a source of anions; and c) a source of phosphine ligands, wherein the solvent is a C1 to C10 alkane or alkene having two or more cyano groups attached.

Procédé d'hydroformylation de composés insaturés en éthylène renfermant au moins 4 atomes de carbone, par mise en réaction de ces composés avec un monoxyde de carbone et de l'hydrogène, en présence d'un solvant et d'un système catalyseur obtenu par combinaison des éléments suivants: a) une source de cations métalliques du Groupe VIII; b) une source d'anions; et c) une source de ligands de phosphine, combinaison dans laquelle le solvant est un alcane ou un alcène C¿1? - C¿10? auquel sont attachés au moins deux groupes cyano.
