Abstract Solubilities of benzene, toluene, nitrobenzene, p-and o-nitrotoluene in dilute aqueous solutions of 18-crown-6 have been determined by UV-spectrometry at 15, 25, and 35°C. The saturation concentration of each aromatic solute depends linearly on the l8-crown-6 concentration. Experimental results show that 18-crown-6 molecules form host-guest complexes (with 1:1 stoichiometry) with the aromatic molecules, which supports the assumption that the force of combination between the crown ether and the aromatic molecules is a weak hydrophobic interaction.
