Contributions of the crosslinked and noncrosslinked moieties to the solvent‐induced swelling of brown coals

Abstract

A suite of brown coals from different sources was examined for solventinduced swelling in two forms : oven-dried whole coal and pyridine-extracted coal. This enabled the swelling to be resolved into the component due to imbibition of solvent by the crosslinked part and the component due to the non-crosslinked part.
