The types of compounds present in aromatic concentrates derived from high-boiling petroleum distillates can be estimated from a gel permeation chromatographic (gpc) analysis by the use of tables developed from extensive gpc and mass-spectral analyses on fractions from four crude oils. For a fraction from the gpc analysis, the retention volume and the molecular weights (from mass spectrometer) suffice to indicate the types of compounds that predominate. The tables that show these qualitative analyses were developed through the use of pure compounds as well as the extensive analyses on Prudhoe Bay (Alaska), Gach Saran (Iran), Swan Hills (Canada), and Wilmington (California) crude oils. These tables provide a rapid method for determining which types of compounds are present in a gpc fraction before attempting to develop quantitative data.
