Functional group analysis in coal and on coal surfaces by NMR (nuclear magnetic resonance) spectroscopy
The purpose of this research is to develop a convenient, sensitive, reliable and rapid technique for the determination of the labile-hydrogen functional group composition of coal and coal-derived materials by the NMR spectroscopy of their derivatives made with regents containing the NMR-active nuclei {sup 31}P, {sup 113}Sn, or {sup 205}Tl. Knowledge of the heteroatom composition of coals is necessary to the development of increasingly sophisticated coal processing technologies. This quarter, the moisture content of several coals was determined. 18 refs., 2 tabs.
