Chromatographic behaviour of aromatic hydrocarbons and heterocyclic compounds on silica gel with a chemically bonded amino phase

Abstract

The chromatographic behaviour of a series of polycyclic aromatic hydrocarbons and heterocyclic compounds was investigated on Separon SIX NH2, a sorbent with chemically bonded amino groups. The effect of substitution and partial hydrogenation of the aromatics on their retention was examined. The achieved separation of aromatic hydrocarbons from their mixtures into groups, each containing substances with the same number of rings, was compared with that published for other, similar chromatographic materials. The effect of structure of some heterocyclic compounds on their affinity for the stationary phase, in comparison with the related aromatic hydrocarbons, is also discussed.
