Abstract

The selective extraction of potassium chloride from aqueous brines containing any or all of the chlorides of sodium, magnesium and calcium, by crown ethers dissolved in substituted phenols is described. The driving force for the transfer of potassium chloride from the aqueous feed through the organic phase into the aqueous strip solutions is the difference in thermodynamic activities of the solute in the two aqueous media. No chemicals are consumed in this process which was tested in a cyclic manner on a laboratory scale with full recovery of the solvent. Losses of the extractant and solvent to the aqueous phases by solubility are minimized by proper choice of these reagents, and the possible use of a diluent. The effects of diluents on the extraction are also presented.
