Excess Molar Enthalpies of Binary Mixtures Containing Lactams, Chlorotoluenes and Benzene
نویسنده
چکیده
Excess molar enthalpies, E H of 1-methyl pyrrolidin-2-one or pyrrolidin-2-one or benzene (i) + oor mor 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 1methyl pyrrolidin-2-one or benzene (i) + oor mor p-chlorotoluene mixtures are positive; and those for pyrrolidin-2-one (i) + oor mor p-chlorotoluene (j) mixtures are negative across full range of composition. The H data have been tested in terms of Graph and Prigogine-Flory-Patterson theories.
