ABSTRACT
Excess heat capacities, oCEP Pijk of {1-methylpyrrolidin-2-one (i) + benzene (j) + o- or m- or p-chlorotoluene (k)} and CEP 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 0.1 MPa 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 CEP and oCEP Pijk values commuted by Graph theory compare well with experimental values.
