Abstract

The separation and characterization of aromatic hydrocarbons from high boiling fractions (>200°C) of Nigeria crude oil is reported. The crude oil was distilled under atmospheric pressure in a glass system, with the help of a paraffin bath. The bottom fraction of the crude oil was fractionated using solvent deasphaltening (in which case n-heptane was used followed by filtration), and elution - adsorption chromatography. The saturates were eluted with n-heptane by liquid chromatography on silica gel while the aromatics were eluted with trichlorethylene. The l.R. analysis of the aromatic extracts showed absorption peaks at 3082.94 cm-1, 3037.06cm-1, 1584.82cm-1, l557.09cm-1, l497.43cm-1, 1247.97cm-1, 931.79cm-1, 907.36cm-1, 841 .53cm-1, 676.46cm-1 and 629.49cm-1 respectively. These absorption peaks are due to the presence of aromatics hydrocarbons
