A comparative study of adsorption of vapors of nitrogen-containing compounds on a microporous clay adsorbent

Differential isosteric heats of adsorption of pyridine and acetonitrile vapors on a dehydrated microporous clay adsorbent with intercalated polyhydroxyaluminum cations have been determined. As has been found from the temperature dependence of adsorption, the transformation of these polycations into...

Summary:Differential isosteric heats of adsorption of pyridine and acetonitrile vapors on a dehydrated microporous clay adsorbent with intercalated polyhydroxyaluminum cations have been determined. As has been found from the temperature dependence of adsorption, the transformation of these polycations into alumina clusters by the thermal treatment of intercalated clay reduces the micropore volume and the heats of pyridine and acetonitrile adsorption.
