Isothermal vapour-liquid equilibria and excess volumes in the methanol-aliphatic ether systems

Vapour-liquid equilibria were measured isothermally in the binary systems containing methanol with butyl methyl ether, tert-butyl methyl ether, ethyl propyl ether, diisopropyl ether and butyl ethyl ether. The data were correlated using the Redlich-Kister, Wilson, and NRTL equations within the accuracy of experimental errors. The excess free volumes of liquid mixtures were determined and correlated at 25 °C.
