✦ Synopsis
The macromolecular network structure of the organic phase of bituminous coals was investigated with equilibrium swelling experiments at 35" and 60°C. It was determined that an oxygen-methylation technique led to cleavage of hydrogen bonds and significant increase of swelling. Pyridine preextraction led to significant differences in swelling due to partial incorporation in the network structure.
