Experimental and molecular-statistical investigation of adsorption of aminoadamantanes on graphitized thermal carbon black

Thermodynamic characteristics of adsorption of some isomeric aminoadamantanes on graphitized thermal carbon black were determined by molecular-statistic calculations and gas-chromatographic measurements. The parameters of the potential function for the pairwise intermolecular interactions between nitrogen in saturated amines and carbon in graphite were calculated. The best agreement between the experimental and calculated Henry constants for 1-aminoadamantane is attained by introducting a correction taking into account the influence of the cage effect on -substituents in the adamantane unit in the parameters of the _N...C(GTCB) atom-atom potential.
