Abstract

Thermodynamic characteristic of sorption (partition constant, standard enthalpies and entropies
of sorption) of adamantane’s derivatives on polymer stationary liquid phases with different polarity were
determined by gas-liquid chromatography (GLC) in a wide range of temperatures in conditions of
limiting small concentration of sorbate in gas phase. The influence of electronic and geometrical structure
of sorbates, nature of sorbents and temperature on values of sorption laws is investigated. The values of
enthalpies of vaprization were determined for some adamantane’s derivatives.
