✦ Synopsis


The (vapour+liquid) equilibria for (ethanol+2-methylpropan-1-ol +acetonitrile+benzene) and for (propan-2-ol+2-methylpropan-1-ol+acetonitrile+benzene), measured with a modified Boublik vapour-recirculating still at the temperature 333.15 K, are reported. The experimental results are analyzed using the UNIQUAC formalism with only binary parameters. 7 1995 Academic Press Limited (1-x2-x3-x4)CH3CH2OH+x2CH3CH(CH3)CH3OH+x3CH3CN+x4C6H6 0.

Vapour pressures of (butanenitrile + propan-1-ol or propan-2-ol) at temperatures T between 278.15 K and 323.15 K were measured by a static method. Excess molar enthalpies and volumes were also measured at T=298.15 K. Following Barker's method, the activity coefficients and the excess molar Gibbs fre
