The investigatin of the structure of molecules by gas adsorption chromatography

Abstract

The sequence of emergence of substances from the surface of graphitized carbon black principally depends on the energy of the nonspecific interaction, which is connected with the orientation of the molecules on the plane surface. This allows us to use graphitized carbon black successfully, not only for the chromatographic analysis of different isomers but also for the identification of structural isomers. Some examples of identification of the cis- and trans-configuration of 3-methylpentene-2 and 3,4-dimethylpentene-2 and of the configurations of cyclic hydrocarbons C₆C₁₂ are given.
