This paper discusses the isolation of n-pentane asphaltenes from a Wilmington, Calif., crude oil and the separation of the asphaltene into fractions of acids, bases, neutral N compounds, saturated hydrocarbons, and aromatic hydrocarbons, using ion exchange chromatography, coordination chromatography, and adsorption chromatography. The major compound types in the acid fraction were identified by infrared spectrometry. Molecular weights were estimated by vapor-phase osmometry, mass spectrometry, and quantitative infrared spectrometry. (DLC)
