Abstract
Vapour–liquid equilibrium data are reported for the binary mixtures formed by cyclohexane and the branched ether 1,1-dimethylethyl methyl ether (tert-butyl methyl ether or MTBE). A Gibbs–Van Ness type apparatus was used to obtain total vapour pressure measurements for cyclohexane–MTBE mixtures at 298.15, 308.15 and 318.15 K. The system exhibits very small deviations from Raoult's law with a nearly ideal behaviour. No temperature effect on vapour compositions is observed. Results are analysed in terms of the Peng–Robinson equation of state and the Wong–Sandler mixing rule, the lattice-fluid model, the UNIQUAC model, and the UNIFAC and modified UNIFAC models.
