摘要: Abstract Carbon-13 Nuclear Magnetic Resonance Spectroscopy has been applied to coal-derived liquids in order obtain additional information regarding molecular structure and composition. The data have demonstrated that, although the chemical is extremely complex, a significant amount of material present form normal paraffinic both as free paraffins alkyl substituents on aromatic hydroaromatic materials. Semiquantitative estimates are made content atom percentage this that must exist unprocessed coal.
