| Abstract: | Summary The behaviour of perfluorocarbon modified silica gel has been investigated in HPLC for the group separation of alkyl-substituted aromatic hydrocarbons. Using dry alkanes as eluents, the influence of the substituted alkyl groups on the retention of mono- and polycyclic aromatics is very small. Therefore, aromatic hydrocarbons can be separated in order of their increasing  -electron energy characterized by a linear correlation between ink and the resonance energy. The method is useful for the group separation of crude oil distillates into groups according to aromatic ring types.Presented at the  14th International Symposium on Chromatography London, September, 1982 . |
