ABSTRACT:
Transition metal hydroxides of the first transitional series are prepared by reacting a transition metal with water, a nitrogen-containing compound, one or more aliphatic or alicyclic monocarboxylic acids containing at least eight carbon atoms and a diluent in the presence of oxygen. Only small amounts of the acid and nitrogen-containing compound are required. The reaction mixture also can contain dispersants. The method of the invention avoids the corrosion and pollution problems which are present in some prior art processes. The transition metal hydroxides prepared in accordance with the invention are free of salt contamination.
