Gas-solid adsorption chromatography of some aromatic hydrocarbons and nitrogen heterocycles on alumina

By means of gas-solid adsorption elution chromatography on alumina, either plain or pre-treated with non-eluting quinclidine, retention times and heats of adsorption were determined for benzene, eight monoalkylbenzenes, m-xylene, naphthalene, and 2,6-lutidine. In general both retention time and heat...

Description
Summary:By means of gas-solid adsorption elution chromatography on alumina, either plain or pre-treated with non-eluting quinclidine, retention times and heats of adsorption were determined for benzene, eight monoalkylbenzenes, m-xylene, naphthalene, and 2,6-lutidine. In general both retention time and heat of adsorption decreased on impregnating the alumina with quinuclidine. For plain alumina various pyridines and quinolines were very strongly retained so long as the non-bonding electrons on the nitrogen atom were not sterically hindered by ring substituents. Results are consistent with data on adsorbabilities obtained earlier from solid-liquid chromatography.
