Zusammenfassung: | This invention is directed to a process for making a salt of a carboxylic acid. The process comprises contacting a catalyst with an alkaline mixture comprising a primary alcohol. In one embodiment, the catalyst comprises a metal supporting structure (preferably a metal sponge supporting structure comprising at least about 10% by weight nickel) having a copper-containing active phase at the surface thereof and iron as a catalyst modifier. The supporting structure is resistant to deformation under the conditions of the dehydrogenation reaction. This invention is also directed to novel nickel-containing catalysts having a copper-containing active phase and iron as a catalyst modifier which may, for example, be used in the above process. This invention is further directed to processes for making such catalysts.
Esta invencion esta dirigida a un procedimiento para elaborar una sal de un acido carboxilico; el procedimiento comprende poner en contacto un catalizador con una mezcla alcalina que comprende un alcohol primario; en una modalidad, el catalizador comprende una estructura de soporte de metal (preferiblemente una estructura de soporte de metal esponjoso que comprende al menos aproximadamente 10% en peso de niquel) que posee una fase activa que contiene cobre en la superficie de la misma y hierro como modificador del catalizador; la estructura de soporte es resistente a la deformacion bajo las condiciones de la reaccion de deshidrogenacion; esta invencion tambien esta dirigida a catalizadores que contienen niquel novedosos que poseen una fase activa que contiene cobre y hierro como modificador del catalizador que se puede utilizar, por ejemplo, en el procedimiento anterior; esta invencion se refiere ademas a procedimientos para elaborar dichos catalizadores. |
