    • 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, for example, the catalyst comprises a metal support (preferably a metal sponge support) coated with copper. The support comprises at least about 10% (by weight) non-copper metal, and the copper-containing coating comprises from about 0.005 to about 0.5 grams of copper (per gram of said metal support). In another embodiment, the catalyst comprises a metal support (preferably a metal sponge support) coated with silver. The support comprises at least about 10% (by weight) non-silver metal, and the silver-containing coating comprises from about 0.005 to about 0.5 grams of copper (per gram of said metal support). In another embodiment, the catalyst comprises at least about 15% (by weight) non-copper metal, and at least about 10% (by weight) copper. In yet another embodiment, the catalyst comprises at least about 15% (by weight) non-silver metal, and at least about 10% (by weight) silver. In both these embodiments, it is particularly preferable for the catalyst to be in the form of a metal sponge. This invention is also directed to copper-containing and silver-containing catalysts which may, for example, be used in the above process. This invention is further directed to processes for making such catalysts.
    • 本发明涉及一种制备羧酸盐的方法。 该方法包括使催化剂与包含伯醇的碱性混合物接触。在一个实施方案中,例如,催化剂包含涂覆有铜的金属载体(优选金属海绵载体)。 载体包含至少约10%(重量)的非铜金属,并且含铜涂层包含约0.005至约0.5克铜(每克所述金属载体)。在另一个实施方案中,催化剂包含 金属支撑体(优选金属海绵支撑体)涂覆银。 载体包含至少约10%(重量)的非银金属,并且含银涂层包含约0.005至约0.5克铜(每克所述金属载体)。在另一个实施方案中,催化剂包含 至少约15%(重量)的非铜金属和至少约10%(重量)的铜。 在另一个实施方案中,催化剂包含至少约15%(重量)的非银金属和至少约10%(重量)的银。 在这两个实施方案中,特别优选催化剂为金属海绵形式。本发明还涉及可以在上述方法中使用的含铜和含银催化剂。 本发明还涉及制备这种催化剂的方法。
