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

A dynamic recirculating still has been used to determine isobaric vapour-li quid equilibrium data for the systems tetrahydrofuran, tetrahydropyran, 2-m ethyl-tetrahydrofuran, and 2,5-dimethyl-tetrahydrofuran + chlorobenzene at 40.0 and 101.3 kPa. The experimental data for all systems were checked for thermodynamic consistency using the point-to-point method of Van Ness, The systems present negative deviations from ideality and none of them show aze otrope, The VLE data have been satisfactorily correlated with the Wilson, N RTL and UNIQUAC equations, Predictions with the ASOG and UNIFAC methods wer e also included.
