“…As an extension to our previous study, 7,8 the present work reports the calorimetric measurement results of the noncovalent bonding interactions between some amino acids (L-valine and L-threonine) and pyridine and methylpyridine. The enthalpic coefficients of interaction of the systems have been calculated according to the McMillan-Mayer model.…”

“…The details of the experimental techniques have been described elsewhere. 7,8 The enthalpy of dilution ∆H dil /J‚kg -1 and final molality m x /kg‚mol -1 are determined by measuring the thermal power P/µW and the flow rates of the solution and the solvent (f A and f B /mg‚s -1 ): in which M x is the molar mass of the solute (kg‚mol -1 ) and m x,i is the initial molality (kg‚mol -1 ).…”

Enthalpies of mixing in aqueous solutions of L-valine and L-threonine with pyridine and methylpyridine isomers and their enthalpies of dilution have been determined by flow microcalorimetry at 298.15 K. The results have been analyzed using the excess function concept, and heterotactic enthalpic pairwise interaction coefficients, h xy , of the virial expansion of the excess enthalpy have been obtained. These are briefly discussed in terms of intermolecular interactions between the hydrated solute species. In addition, the results obtained in the present paper along with literature data have been treated in terms of the Savage-Wood additivity group (SWAG), and values of the functional group interaction parameters for R-amino acids + pyridine and R-amino acids + methylpyridine systems have been estimated. The SWAG approach has been appraised in terms of the results obtained.
