Composition and method for preparing amino acid chelates and complexes free of interfering complex ions

摘要

A composition and method of preparing amino acid chelates and complexes free of interfering ions by blending an amino acid ligand, a calcium oxide and/or hydroxide, and a hydrated metal sulfate salt, placing the blend in a closed environment, heating the blend, and allowing the blend to react is disclosed and described. By heating at low to moderate temperatures in an enclosed environment, the waters of hydration of the metal salt are retained in the enclosed environment and serve to provide the moisture necessary to enable a bonding reaction to take place between the electron rich functional groups of the ligand and the metal ion of the hydrated metal sulfate salt. Additionally, calcium sulfate is formed which can be maintained in the final product.
