As a basic study of solvent extraction of metals with high molecular-weight amines, the measurement of the distribution equilibrium of zinc chloride between Amberlite LA-2, long-chain secondary alkylamine (n-lauryl trialkylmethylamine), dissolved in n-hexane and an aqueous solution of hydrochloric acid was carried out at 30°C over wide concentration ranges of amine, zinc chloride and hydrochloric acid. It was clarified that zinc chloride is extracted by the following reaction: ZnCl2(aq.)+(BH Cl)2(org.)→←(BH)2ZnCl4(org.) The equilibrium constant for this reaction and the stability constants of the chloro complexes of zinc were determined.
