Uses a combination of chromatographic, chemical, and spectroscopic methods to determine the composition of the paraffinic and naphthenic hydrocarbons recovered from asphalts. Monitors the completeness of separation of the hydrocarbons from the aromatics on the basis of UV spectra. Finds that in the mixture of adduct-forming hydrocarbons, along with the n-paraffins there were admixtures of isoparaffins and longchain alkylnaphthenes. Concludes that a comparison of the structural-group composition of the asphalt fractions from the different crudes shows that there are only slight differences in the structure of the paraffinic/naphthenic hydrocarbons present in these asphalts, particularly with regard to those hydrocarbons that do not react with urea.
