A new proton n.m.r. technique has been developed for the chemical characterization of polymerized petroleum pitches with pyridine-insoluble contents as high as 80%. The polymerized pitches were completely solubilized for conventional 1 H n.m.r. evaluation in a mixed solvent system consisting of S$&-

As part of a study to evaluate the potential of shale oils for lubricating oil production, samples from the Rundle and Stuart oil shale deposits in Australia have been processed to produce a range of products which were then characterized by 'Hand 13C high resolution nuclear magnetic resonance (n.m.
Solvent-refined lignite (SRL) and bituminous coals (SRC) are only partially soluble in good standard carbon-13 n.m.r. solvents. A survey of other possible solvents for SRLs and SRCs showed thatsymtriazine at 86ยฐC solvated SR L as well as pyridine, but did not absorb in the regions of interest (5-60
