| description | The invention discloses a method for filtering a three-phased reaction mixture, comprising a liquid phase, an undissolved solid catalytic phase and a gas phase. More precisely it consists tangentially in filtering on one membrane filter at least one part of a three-phased reaction mixture comprising one liquid phase in which are found nitrile functions, one gas phase comprising hydrogen and one solid catalytic phase comprising nickel and/or Raney cobalt, or a supported metal catalyst, in recycling the catalyst while recuperating at least one part of the filtrate comprising the reaction products.
Opisuje sa spôsob filtrácie trojfázovej reakčnej zmesi, obsahujúcej kvapalnú fázu, nerozpustnú pevnú katalytickú fázu a plynnú fázu. Hlavne vynález spočíva v tom, že sa vykoná tangenciálna filtrácia na membránovom filtri aspoň časti trojfázovej reakčnej zmesi obsahujúcej kvapalnú fázu, v ktorej sa nachádzajú nitrilové funkcie, plynnú fázu obsahujúcu vodík a katalytickú pevnú fázu obsahujúcu Raneyov nikel a/alebo kobalt alebo kovový katalyzátor uložený na nosiči, a recyklovaní katalyzátora pri súčasnej izolácii aspoň časti filtrátu obsahujúceho reakčné produkty. ŕ |
