The Chemistry and Applications for the Solubilization of Chromate Salts in Nonpolar Organic Media. Part 1

Abstract

Potassium chromate has been dissolved in significant concentrations in nonpolar organic solvents with the aid of macrocyclic polyether complexing agents. When a two phase system of chromate in water and polyether in organic solvent is agitated, the fraction of salt which is complexed into the organic phase is found to be inversely dependent on the pH of the aqueous phase. Application of this chemistry towards improving organic materials shows promise. TT-E-489F alkyd enamels containing small amounts of dissolved chromate show marked superiority over unmodified enamels in protecting aluminum, steel, and magnesium surfaces from the corrosive effects of long term 5% salt spray exposure.
