Abstract

See full text

The invention concerns a novel process for the production of a complex cound comprising an amino-dicarboxylic acid ion component, a bivalent metal ion component, and a halogen ion component, which comprises the step of reacting together in an aqueous medium an amino-dicarboxylic acid compound, a bivalent metal compound, and a halogen compound, the proportions of said compounds being chosen so that one of each of said ion components is comprised in the aqueous medium, the bivalent metal compound being selected from the oxide, hydroxide, carbonate or a halide of the bivalent metal, and the halogen compound being said halide of the bivalent metal or a hydrogen halide. Certain of the complexes are novel and find use in a variety of medical and veterinary fields.
