Popis:	A number of non-ionic compounds have been found to form solid complexes with 18-crown-6. The highest efficiencies of isolation and the highest selectivities were obtained with nitromethane, dimethyl carbonate and dimethyl oxalate. The usefulness of these compounds was demonstrated in the isolation of >98% pure 18-crown-6 from crude reaction mixtures.
