- Summary
- Unexpectedly low results were obtained for extraction of chlorides, perchlorates, nitrates, and thiocyanates of alkalis, alkaline earths, and actinides from aqueous solutions by water-immiscible solutions of crown ethers. The expected preference for ions matching the crown ether hole-size was not seen here or in solubilizing dry alkali chlorides. Addition of an organic-soluble acid increased alkali extraction, with preference for the ion sized to fit the crown ether. Addition of an organic-soluble alcohol or phenol increased extraction of KCl. Alcohol system results indicated an adduct of one crown ether and one or two alcohol molecules per KCl.
