Title (EN) PURIFICATION OF METALLOCENES
(FR) PURIFICATION D'ALLIAGES ORGANOMETALLIQUES
Abstract: front page image
(EN)Metallocenes, such as silicon bridged ansa-metallocenes, are purified by heating a slurry of the metallocene at elevated temperature in an aprotic, polar solvent so as to extract impurities from the metallocene into the solvent and then separating the impurity containing solvent from the metallocene.
(FR)On purifie des alliages organométalliques, tels que des alliages organométalliques ansa pontés en chauffant un alliage organométallique sous forme de boue liquide à une température élevée dans un solvant aprotique, polaire de manière à extraire les impuretés de l'alliage organométallique en les transférant au solvant puis à séparer le solvant contenant les impuretés de l'alliage organométallique.
