Abstract
A new host compound of the onium salt type,N-(3-biphenylmethyl)quininium bromide (1), is described. This host compound shows an unusually high selectivity for the inclusion of ethanol. Using this clathrand, ethanol can be extracted from a variety of solvent mixtures. In most cases, a remarkable enrichment of the ethanol is observed. The following solvents in a mixture with ethanol remain in the mother liquid: methanol,n-propanol,n-hexane, pyridine.
