Abstract

Excess molar enthalpy (HmE) have been measured at 303.15K for 1-propanol+benzene or toluene or o- or m- or p-xylene mixtures using flow micro calorimeter. The HmE versus x1 plots are skewed toward y-axis showing maxima at x1≈0.3. At (x1=0.5) HmE vary in the order: toluene<benzene<m-xylene<p-xylene~o-xylene. The excess volume data have also been interpreted in terms of Graph-theoretical approach and Prigogine-Flory-Patterson theory. It has been observed that while PFP theory fails to predict the HmE values for these systems in the composition range x1<0.5, agreement with experimental values is reasonably good thereafter. The HmE values calculated by Graph theory compared well with the corresponding experimental values.
