Аннотация: Abstract The adsorption properties of MgO, which is used as a sorbent and catalyst support, were studied using gas chromatography. The test absorbents used were n-alkanes (which show only nonspecific dispersion interactions when physisorbed on any adsorbent) and adsorbates whose molecules are capable of specific interactions with the surface reactive sites of MgO. Adsorption isotherms were measured for CHCl3, CH3NO2, CH3CN, (CH3)2CO, CH3COOC2H5, and (C2H5)2O on MgO at 50–100°C. Differential molar enthalpy changes (−ΔH), equal to molar heats of adsorption, were determined. For polar adsorbates, contributions from dispersive and specific interactions into −ΔH were determined. The electron-acceptor and electron-donor abilities of the MgO surface were estimated.
