ABSTRACT

The paper reports accurate experimental data of vapour-liquid equilibria at T = 313.15 K, using an isothermal total pressure cell, for the binary systems (1-pentanol + cyclohexane) and (1-pentanol + toluene). The data were correlated using Margules, Wilson, NRTL and UNIQUAC equations. Also, the enthalpies of mixing were measured for the same systems at two different temperatures T = (298.15 and 313.15) K using an isothermal flow calorimeter and the excess enthalpies were correlated by the Redlich-Kister equation. The thermodynamic behaviour of both systems is discussed.
