Title
(DE) VERFAHREN ZUR OXIDATION VON METHAN
(EN) METHOD FOR OXIDIZING METHANE
(FR) PROCÉDÉ D'OXYDATION DU MÉTHANE
Abstract
(DE)
Es werden Platin(ll)komplexe und die Verwendung dieser Komplexe zur Oxidation von Methan zu Methylsulfat offenbart, wobei der Katalysator als Liganden ein Netzwerk auf Basis von aromatischen N-Heterocyclen ist, welches mindestens 2 koordinative N-Atome pro Platinatom aufweist und das Komplexanion ausgewählt ist aus einem Halogenid. Der Katalysator ermöglicht eine selektive Niedrigtemperatur-Oxidation von Methan zu Methylsulfat bzw. Methanol. Die Katalysatoren zeigen nicht nur hohe Aktivität, sondern können leicht vom Reaktionsgemisch abgetrennt und über etliche Läufe ohne signifikanten Aktivitätsverlust wiederverwendet werden.
(EN)
The invention relates to platinum(II) complexes and the use of said complexes to oxidize methane to form methyl sulfate, wherein the catalyst as a ligand is a network based on aromatic N heterocycles, which network has at least 2 coordinate N atoms per platinum atom, and the complex anion is selected from a halide. The catalyst enables a selective low-temperature oxidation of methane to form methyl sulfate or methanol. The catalysts not only exhibit high activity but also can be easily separated from the reaction mixture and reused over several runs without a significant loss of activity.
(FR)
La présente invention concerne des complexes de platine (II) et l'utilisation de ces complexes pour l'obtention de méthylsulfate par oxydation de méthane. En l'occurrence, le catalyseur, qui se présente sous forme de ligands formant un réseau à base de noyaux aromatiques N-hétérocycliques, comporte au moins deux atomes de coordination en N pour chaque atome de platine, l'anion de complexe étant choisi dans les halogénures. Ce catalyseur permet une oxydation sélective à basse température du méthane en méthylsulfate, voire même en méthanol. Ces catalyseurs, d'une part font preuve d'une activité élevée, d'autre part sont faciles à séparer du mélange de réaction, et enfin sont réutilisables plusieurs fois, sans perte notable d'activité.
