Hydroxyl contents of coals: new data and statistical analyses
Abstract
Data previously published for the phenolic hydroxyl content of 35 coals have been supplemented by the study of a further 17 samples. Various statistical analyses have now been made of the relationship of the data for the full set of 52 samples to other properties of the coals. Hydroxyl contents can be expressed either as fractions of total organic matter or of the total organic oxygen in the coals. Data expressed on the first of these bases exhibit a strong dependence on the degree of metamorphism of the coals, while those on the second basis do not. Statistical correlations on either basis show that systematic relations between coal properties differ for different coal provinces of the U.S.A. thus demonstrating that the properties of a coal are dependent to an important extent on the geology and geochemistry of the basin in which it is found.
