Thermodynamics of solution of some nonelectrolyte solutes at infinite dilution in N-methylpyrrolidone stationary phase by gas liquid partition chromatography

Abstract

Thermodynamic properties of solution (∆<i>G</i>_s, ∆<i>H</i>_{s ,}∆<i>S</i>_{s ,}∆<i>G</i>_e, ∆<i>H</i>_eand ∆<i>S</i>_e) at infinite dilution of seventeen nonelectrolytes in N-methylpyrrolidone stationary phase have been determined using gas-liquid partition chromatography at 37, 45 and 55°C. The results are discussed in terms of thermodynamic interactions between the components of the binary nonelectrolyte solutions and the nature of pure components at molecular level.
