Isobaric vapour–liquid equilibrium of binary mixtures of some cyclic ethers with chlorocyclohexane at 40.0 and 101.3 kPa

Isobaric vapour–liquid equilibrium data for the binary systems formed by tetrahydrofuran, tetrahydropyran, 2-methyl-tetrahydrofuran, and 2,5-dimethyl-tetrahydrofuran with chlorocyclohexane have been measured at 40.0 and 101.3 kPa using a dynamic recirculating still. All experimental data were checked for thermodynamic consistency by means of the Van Ness method. The systems studied present slightly deviations from ideal behaviour. None of them show azeotrope. The VLE data have been satisfactorily correlated with the equations of Wilson, NRTL and UNIQUAC. Predictions with the ASOG and UNIFAC group contribution methods are included.
