  • Descrição: •The CPE and (CPE)ijk data have been measured over entire mole fraction at 3 temperature.•The CPE and (CPE)ijk data have been fitted to Redlich–Kister equation.•The observed data have been analyzed in terms of Graph theory.•The CPE and (CPE)ijk values calculated by Graph theory compare well with experimental values. Excess heat capacities, (CPE)ijk of {1-methylpyrrolidin-2-one (i)+benzene (j)+o- or m- or p-chlorotoluene (k)} and CPE of their sub-binary {1-methylpyrrolidin-2-one (i)+benzene (j)}; {benzene (i)+m- or p-chlorotoluene (j)} mixtures have been determined using their measured heat capacities data at T=(293.15, 298.15, 303.15)K and 0.1MPa using micro differential scanning calorimeter. The results are discussed in terms of Graph (which deals with the topology of the constituent molecules) theory. The results suggest that CPE and (CPE)ijk values commuted by Graph theory compare well with experimental values.
