Title (EN) METHOD FOR REACTIVATING A HOMOGENEOUS OXIDATION CATALYST
(FR) PROCÉDÉ DE RÉACTIVATION D’UN CATALYSEUR D'OXYDATION HOMOGÈNE
(DE) VERFAHREN ZUR REAKTIVIERUNG EINES HOMOGENEN OXIDATIONSKATALYSATORS
Abstract:
(EN) The invention relates to a method for reactivating homogeneous catalyst systems from organic reaction mixtures. The catalyst systems are suitable for oxidating organic compounds such as, for example cyclododecene. The reactivation is carried out by means of an aqueous base.
(FR) La présente invention porte sur un procédé de réactivation de systèmes catalytiques homogènes contenus dans des mélanges réactionnels organiques. Ces systèmes catalytiques conviennent à l’oxydation de composés organiques tels que le cyclododécène par exemple. La réactivation est réalisée au moyen d'une base aqueuse.
(DE) Die vorliegende Erfindung betrifft ein Verfahren zur Reaktivierung homogener Katalysatorsysteme aus organischen Reaktionsmischungen. Die Katalysatorsysteme eignen sich für die Oxidation organischer Verbindungen wie beispielsweise Cyclododecen. Die Reaktivierung erfolgt mittels wässriger Base.
