    Jun 01, 1980  Heats of immersion (h i) of coals have been shown to be a valuable means of investigating structure and chemistry of coals.This report outlines some of the factors involved. Lower ranked coals imbibe more liquids (i.e., H 2 O) onto more polar sites (carbonyl, phenolic, etc.) than higher ranked coals. Mineral matter reacts strongly with polar liquids (i.e., H 2 O) giving rise to enhanced h i.
