Description/Abstract Three consecutive treatments of Illinois No. 6 coal with K-CE (potassium-crown ether) reagent had resulted in a total of 52% solubilized coal and confirms our previous results. The reaction of 2-naphthol with K-CE reagent produced 2-tetralone, 5,8-dihydro-2-naphthol and 5,6,7,8-tetrahydro-2-naphthol as the major products. This model compound results explain the appearance of carbonyl absorptions in the coal-K-CE reaction extracts and suggests that reduction of naphthol units to tetralone structures as a major reaction pathway in the coal-K-CE reaction. Reaction of coal (THF-1) with semicarbazide-bonded-silica gel resulted mainly in an irreversibly binding of the coal to the silica-gel.
