ABSTRACT:
Novel water-soluble inorganic multi-metal polymeric complexes are obtained by reacting, in the presence of water, at least one non-alkaline metal selected from Groups I to VIII of the Periodic Table with an alkali metal hydroxide and a phosphorus-containing compound which is capable of providing active hydrophosphide groups to the reaction under the conditions prevailing in the aqueous reaction medium. In one embodiment, an excess of the non-alkaline metal or metals is introduced into a reaction vessel, already containing an aqueous solution of a phosphorus-containing acid, and the alkali metal hydroxide is thereafter incrementally added. In another embodiment, carried out under high pH conditions, the alkali metal hydroxide and phosphorus-containing compound are each incrementally added to the reaction medium. The inorganic multi-metal polymeric complexes produced by this reaction are uniquely characterized by their ready solubility in water to produce transparent, viscous solutions which have valuable utility in the plating of metals and the precipitation of high purity metals and metallic pigments from the aqueous solutions.
