✦ Synopsis
A low-rank coal is examined for swelling in benzene-pyridine and toluene-pyridine mixtures. In each case, swelling is shown to be mainly due to the pyridine, the action of which is specific and not amenable to interpretation by the solubility parameter approach to understanding coal swelling.
