Sekundarni naslov: | DETERMINATION OF FREE ENERGY OF ALCOHOLS USING CAPILLARY GAS CHROMATOGRAPHY |
Sekundarni povzetek: | The aim of our work was to determine the change of the standard free energy of alcohols in the distribution between the mobile and stationary phase. Values were determined based on different retention times of a homologous series of alcohols from butan-1-ol to octan-1-ol, and including also decan-1-ol. For measurements, we used a gas chromatograph with a capillary column. We have found the linearity of the standard free energy according to the change of temperature of the capillary column and the linearity with respect to the homologous series of alcohols at a constant temperature. By measuring at different pressures, we have shown that the thermodynamic equilibrium constant is independent of pressure. In the course of the procedure for the calculation of the standard free energy, we have defined other standard enthalpy and standard entropy values. The data can be used to simulate similar separation methods, and in particular in education in the field of thermodynamics and chemical equilibrium. |
