Abstract

Excess molar enthalpies, E H of 1-methyl pyrrolidin-2-one or pyrrolidin-2-one or benzene
(i) + o- or m- or p-chlorotoluene (j) binary mixtures have been measured over entire
composition range at 298.15 K using high sensitivity differential scanning calorimeter
Micro DSC (Model – μDSC 7 Evo). The E H data have been fitted to Redlich-Kister
equation to estimate binary fitting parameters and standard deviations. The E H of 1-
methyl pyrrolidin-2-one or benzene (i) + o- or m- or p-chlorotoluene mixtures are
positive; and those for pyrrolidin-2-one (i) + o- or m- or p-chlorotoluene (j) mixtures are
negative across full range of composition. The HE data have been tested in terms of
Graph and Prigogine-Flory-Patterson theories.
