Excess heat of mixing of pyridine bases with toluene

Experimental results and theoretical description

Journal of Thermal Analysis and Calorimetry
Authors: H. Wilczura, T. Kasprzycka-Guttman, and A. Myslinski

Abstract  

The excess heats of mixing of pyridine bases with toluene at 298.15 K were measured, and the Prigogine-Flory-Patterson theory was applied to describe the experimental results.

The intermolecular interactions in binaries

Pyridine base + hydrocarbon, on the base of experimental enthalpy of mixing data

Journal of Thermal Analysis and Calorimetry
Authors: H. Wilczura, T. Kasprzycka-Guttman, M. Jarosz-Jarszewska, and A. Myslinski

Abstract  

The recapitulation of systematical investigations of excess enthalpy of mixing in binary mixtures: pyridine base +n-alkane or some of arenes is presented. On the base of experimental results as well as model calculations (PFP, ERAS) the discussion of intermolecular interactions in pyridine bases is given.

The excess enthalpy of mixing versus composition was studied at 293.15 K and 303.15 K for some binary mixtures of methanol with pyridine bases. The results are presented in Tables.
