✦ Synopsis

The adsorption chromatography of aromatic hydrocarbons was studied for the adsorption system alumina-n-pentane.

The importance of the planarity of the molecules, acid-base interactions of some types of hydrocarbons with the alumina surface and alkylation at different positions in polynuclear aromatics was shown. A series of standards was selected with fixed values of retention indices. The retention indices of the other aromatic hydrocarbons were calculated by means of interpotation or extrapolation, as with Kovits indices in gas chromatography.
