A homogenous process for the hydrogenation of the carboxylic acids and/or derivatives thereof in the presence of a catalyst comprising ruthenium, rhodium, iron, osmium or palladium, and an organic phosphine is described in which the hydrogenation is carried out in the presence of at least about 1% by weight water. A process for regenerating a catalyst comprising ruthenium, rhodium, iron, osmium or palladium and an organic phosphine is also described in which the regeneration is carried out in the presence of hydrogen and water.
描述了一种在由钌、铑、铁、锇或钯和有机膦组成的催化剂存在下对羧酸和/或其衍生物进行氢化的均质工艺,其中氢化是在至少约1%(重量)水存在下进行的。还描述了一种再生由钌、铑、铁、锇或钯和有机膦组成的催化剂的工艺,其中再生是在氢和水的存在下进行的。
