Abstract
(DE)
Die Erfindung betrifft ein Verfahren zur katalytischen Hydrierung einer organischen Verbindung, insbesondere einer labilen organischen Verbindung, in Gegenwart eines Trägerkatalysators mit einer Ruthenium als Aktivmetall und insgesamt 0,01 bis 30 Gew.-% Aktivmetalle enthaltenden Beschichtung. Erfindungsgemäß lassen sich eine höhere Stereoselektivität und höhere Katalysatorstandzeit erhalten, wenn man einen Trägerkatalysator verwendet, dessen oxidisches, carbidisches, nitridisches oder silikatisches Trägermaterial vor der Beladung mit mindestens einem Aktivmetall eine BET(N2)-Oberfläche von weniger als 10 m2/g, besonders bevorzugt 0,1 bis 5 m2/g, aufweist und Diatomeenerde mit einer BET(N2)-Oberfläche von grösser 2 m2/g ausgeschlossen wird und dessen Rutheniumgehalt mindestens 50 Gew.-%, vorzugsweise mindestens 99 Gew.-%, der Aktivmetalle ausmacht. Die Erfindung betrifft ferner die genannten Trägerkatalysatoren. Besonders eignen sich das Verfahren und die Katalysatoren zur Hydrierung von mehrfunktionellen Verbindungen, wie Hydroxycarbonylverbindungen und aromatischen Aminen.
(EN)
The invention relates to a method for catalytically hydrating an organic compound, especially an unstable organic compound, in the presence of a supported catalyst that is provided with a coating that contains ruthenium as the active metal and a total of 0.01 to 30 % by weight of active metals. The aim of the invention is to increase stereoselectivity and catalyst service life. To this end, a supported catalyst is used whose oxide-, carbide-, nitride- or silicate-containing support material, prior to being charged with at least one active metal, has a BET(N2) surface of less than 10 m2/g, preferably 0.1 to 5 m2/g, with the exception of diatomaceous earth with a BET(N2) surface of greater 2 m2/g, and whose ruthenium content constitutes at least 50 % by weight, preferably at least 99 % by weight, of the active metals. The invention further relates to the aforementioned supported catalysts. The method and catalysts according to the invention are especially suitable for hydrating polyfunctional compounds such as hydroxycarbonyl compounds and aromatic amines.

La présente invention concerne un procédé permettant l'hydratation catalytique d'un composé organique, notamment d'un composé organique labile, en la présence d'un catalyseur de support comportant un revêtement contenant du ruthénium en tant que métal actif et en tout de 0,01 à 30 % en poids de métaux actifs. Selon l'invention, une stéréosélectivité élevée et une durée d'action de catalyseur élevée peuvent être obtenues lorsque l'on se sert d'un catalyseur de support dont la substance de support contenant de l'oxyde, du carbure, du nitrure ou du silicate, présente, avant l'adjonction d'une charge contenant au moins un métal actif, une surface BET(N2) inférieure à 10 m2/g, de préférence de 0,1 à 5 m2/g, la terre diatomée ayant une surface BET(N2) supérieure à 2 m2/g étant exclue, et la teneur en ruthénium dudit catalyseur valant au moins 50 % en poids, de préférence au moins 99 % des métaux actifs. Cette invention concerne également les catalyseurs de support mentionnés. Le procédé et les catalyseurs conviennent particulièrement à l'hydratation de composés à fonctions multiples tels que les composés hydroxycarbonyle et les amines aromatiques.
