Experimental study and ERAS modeling of the excess molar enthalpy of (acetonitrile + 1-heptanol or 1-octanol) mixtures at (298.15, 313.15, and 323.15) K and atmospheric pressure

摘要

As a continuation of our studies on excess functions of binary systems, experimental data of excess molar enthalpy of (acetonitrile + 1-heptanol or 1-octanol) mixtures have been determined as a function of composition at (298.15, 313.15, and 323.15) K at atmospheric pressure using a modified 1455 PARR mixture calorimeter. The is positive for both systems over the whole composition range. The applicability of the ERAS-Model to correlate of the mixtures studied was tested. The agreement between experimental and calculated values is satisfactory.
