Notes:
Liquid - liquid extraction with N-methyl-2-pyrrolidone, combined with solid-phase extraction on silica gel using n-pentane and dichloromethane as solvents, has been used for the isolation and concentration of the aromatic fraction from lubricating oil.The identification of individual compounds in this aromatic fraction was performed by capillary gas chromatography-mass spectrometry (CGC-MS) and by determination of retention indices. Quantitative results were obtained by flame ionization detection (CGC-FID). Eighty four compounds, predominantly naphthalenes, phenanthrenes, biphenyls, fluorenes, dibenzo-thiophenes, and their alkylated derivatives, have been identified in a commercial lubricating oil. The total amount of the aromatic fraction did not exceed 0.04 % of the oil.
