ABSTRACT:
In one embodiment, the invention relates to a catalyst in powdered form comprising the oxides of copper, iron, aluminum and manganese wherein the atomic ratio of copper to iron is at least 1:1. In another embodiment, the invention relates to a process for preparing such hydrogenation catalysts which comprises the steps of
(A) preparing a first aqueous solution containing at least one water-soluble copper salt, at least one water-soluble iron salt, and at least one water-soluble manganese salt;
(B) preparing a second solution containing at least one water-soluble basic aluminum salt and at least one alkaline precipitating agent;
(C) mixing the first and second solutions wherein an insoluble solid is formed;
(D) recovering the soluble solid; and
(E) calcining the recovered solid to form the desired catalyst.
The invention also relates to a process for hydrogenating aldehydes, ketones, carboxylic acids and carboxylic acid esters.
