ABSTRACT

The excess heat capacities, CPE of 1-methylpyrrolidin-2-one (1) + o-, m-, or p-chlorotoluene (2) and pyrrolidin-2-one (1) + o-, m-, or p-chlorotoluene (2) binary mixtures have been measured as a function of composition at (293.15, 298.15, and 303.15) K using microdifferential scanning calorimetry. The CPE data have been fitted to Redlich Kister equation to calculate binary adjustable parameters and standard deviations. The measured properties of the studied mixtures have been analyzed in terms of Graph theory (which deals with the topology of the constituent of mixtures). It has been observed that Graph theory describes well the CPE data of the investigated binary mixtures.
