The liquid–vapor equilibrium in the toluene–methanol–N-octylquinolinium bromide system has been studied at 101.3 kPa and various concentrations of the organic salt. It was shown that the quinolinium salt can be used as a separating agent for a toluene–methanol azeotrope mixture. For breaking the azeotrope and separating the mixed solvent into components, the N-octylquinolinium bromide concentration (in mole fractions) should be 0.55 or higher.
