Popis: The inclusion properties of dibenzo-24-crown-8 ether were studied in gas-solid chromatography (GCS) and gas-liquid chromatography (GLC) systems. Substances potentially capable of interacting with the cavity of the crown ether —homologous series of alkanes, alcohols, ethers, aromatics and halogenated hydrocarbons—were used as the sorbates and solutes. It was found that inclusion compounds are formed with methanol, ethanol, dichloromethane, trichloromethane, 1,2-dichloroethane, diiodomethane and the aromatic nucleus of aromatics under conditions used in the GSC system and with dichloromethane, trichloromethane, 1,2-dichloroethane, diiodomethane and the aromatic nucleus of aromatics in the GLC system.
