The concentration of different oxygen-containing groups (-OH, COOH, Ar-0-Ar, Ar-0-CH,, R-HO-R) in two different coal types (a brown coal and a flame coal) are described by combined use of quantitative 13C CP/MAS n.m.r. spectroscopy and several labelling reactions (acetylation, silylation, methylatio

The thermodynamic equilibrium constants for the reduction of oxygen and sulphur functional groups in hydrogen and in tetralin were calculated for the temperature range 327-527ยฐC. All the reduction reactions of the oxygen groups are thermodynamically favourable both with hydrogen and with tetralin.
