Resumo

Two kinds of four-component solubility isotherms consisting of (Λ-[Co(ox)(en)2]+, Δ-[Co(ox)(en)2]+)–(Cl−, X−)–H2O, where X− stands for Δ-[Co(edta)]− or (R,R)-C4H5O6−, have been determined experimentally at 25 °C. It has been found that neither double salt nor solid solution exists and no configurational activity is observed in these systems. The applications of these phase diagrams to the practical optical resolutions are discussed.
