The Bureau of Mines has developed a systematic procedure for separation, characterization, and semiquantitative analysis of high- boiling (350 deg to 550 deg c) distillates of crude oils. Isothermal and molecular distillation were used to prepare the 370 deg to 530 deg c distillate of Recluse, Wyoming, crude oil. The distillate was separated into fractions by chemical treatment, silica-alumina gel adsorption, and gel permeation chromatography (gpc). The fractions were analyzed by use of gpc correlations and mass and nuclear magnetic resonance (nmr) spectrometry. The increased knowledge of petroleum composition obtained from the data will contribute to improved petroleum processing and utilization and energy conservation.
