Patent

CA 2578193

Disclosed is a method for telomerizing non-cyclic olefins comprising at least two conjugated double bonds with at least one electron donor by using a catalyst that contains a metal from group 8, 9, or 10 of the periodic table of elements. The inventive method is characterized in that the entire telomerization process includes a catalyst recirculation step in which hydrogen is added to the mixture provided in said step via a hydrogen source.

L'invention concerne un procédé de télomérisation d'oléfines non cycliques dotées d'au moins deux doubles liaisons conjuguées avec au moins un nucléophile au moyen d'un catalyseur comportant un métal du groupe 8, 9 ou 10 de la classification périodique des éléments. L'invention est caractérisée en ce que le procédé de télomérisation dans son ensemble comporte une opération de recyclage catalytique durant laquelle de l'hydrogène est introduit par une source d'hydrogène dans le mélange utilisé lors de cette opération.
