METAL-DOPED SULFONATED ION EXCHANGE RESIN CATALYSTS
A method for preparing ketones in greater yield and selectivity compared to previous catalyzed reactions by acid-catalyzed condensation reaction using a metal-doped polysulfonated ion exchange resin catalyst is disclosed. For example, use of polysulfonated ion exchange resins having at least 5.0 mil...

| description | A method for preparing ketones in greater yield and selectivity compared to previous catalyzed reactions by acid-catalyzed condensation reaction using a metal-doped polysulfonated ion exchange resin catalyst is disclosed. For example, use of polysulfonated ion exchange resins having at least 5.0 milliequivalents sulfonic acid groups/gram catalyst and loaded with metal, such as palladium, provides enhanced yields of methyl isobutyl ketone from the condensation reaction of acetone compared to use of conventional monosulfonated ion exchange resin catalysts.
Se describe un metodo para preparar cetonas con mayor rendimiento y selectividad en comparacion con reacciones catalizadas previas por una reaccion de condensacion catalizada por acido, utilizando un catalizador de resina de intercambio de iones polisulfonada adulterada con metal. Por ejemplo, uso de resinas de intercambio de iones polisulfonadas que tienen al menos 5.0 miliequivalentes de grupos de acido sulfonico/gramo de catalizador y cargadas con metal, tales como paladio, proporciona rendimientos mejorados de metil isobutil cetona a partir de la reaccion de condensacion de acetona en comparacion con el uso de catalizadores de resina de intercambio de iones monosulfonados convencionales. |
