Abstract

Molar heat capacities, CP for 1-methylpiperidine (1) + pyrrolidin-2-one (2) + pyridine, α-, β-, γ-picoline (3) mixtures have been assessed at 293.15, 298.15, 303.15, 308.15 K temperatures and same have been employed to compute excess molar heat capacities, CPE. The CPE data have been allied with the composition of the component molecules (Redlich–Kister expansion) and ternary adjustable parameters calculated along with standard deviations. CPE have been verified in terms of Graph theory. Obtained results inferred that commuted CPE values compare favorably well with measured data. Agreement between experimental and calculated CPE values suggest that several assumptions made in driving CPE data are valid.
