The extractions of 15-crown-5, 18-crown-6, or their silver(I) or lithium(I) complexes as picrates from lithium salt solutions into chloroform have been studied at 25 °C. The extractions of these crown ethers were impaired by an increase in the lithium perchlorate or nitrate concentration. A small salting-out effect was observed in the presence of lithium chloride. The extraction of silver(I) was also impaired by the addition of lithium perchlorate or nitrate. In the lower-concentration region of the lithium salts, the extraction of silver(I) was affected more markedly than that of crown ether itself.
