Thermodynamic study of the behaviour of two molten organic salts as stationary phases in gas chromatography

The gas chromatographic retention behaviour of hydrocarbons of different types and of a group of halogenated compounds was measured at four temperatures from 20 to 30°C in columns containing ethylammonium nitrate (EAN) or n-propylammonium nitrate (PAN) as stationary phases. Thermodynamic functions o...

Description
Summary:The gas chromatographic retention behaviour of hydrocarbons of different types and of a group of halogenated compounds was measured at four temperatures from 20 to 30°C in columns containing ethylammonium nitrate (EAN) or n-propylammonium nitrate (PAN) as stationary phases. Thermodynamic functions of solution calculated from these data are compared to those in non-ionic organic solvents and in water. The solvent behaviour of both molten salts fits well with those of other solvents of high cohensive energy. Alkanes and olefins are retained by mixed processes of solution and adsorption at the gas-liquid interface.
