Title (EN) CATALYST COMPOSITIONS COMPRISING A RUTHENIUM OR OSMIUM CARBENE COMPLEX AND A TERMINAL OLEFIN AND THEIR USE FOR HYDROGENATION OF NITRILE RUBBER
(FR) COMPOSITIONS CATALYTIQUES ET LEUR UTILISATION POUR L'HYDROGÉNATION DE CAOUTCHOUC NITRILE
Abstract: front page image
(EN)This invention relates to novel catalyst compositions based on ruthenium or osmium carbene-complex catalysts, pref. of the Grubbs- I, -II or -III type or fluorenylidene analogues thereof, and terminal olefins, pref. enol ethers such as ethyl vinyl ether (EVE or VEE) as co-catalysts and to a process for selectively hydrogenating nitrile rubbers in the presence of such catalyst compositions, pref. with a preceding metathesis step using the same complex catalyst as in the hydrogenation step.
(FR)L'invention concerne de nouvelles compositions catalytiques à base de catalyseurs complexes, à base de ruthénium ou d'osmium, et de cocatalyseurs spécifiques ainsi qu'un procédé d'hydrogénation sélective de caoutchoucs nitrile en présence de telles compositions catalytiques.
