A series of control experiments using potassium, crown ether and tetrahydrofuran in the absence of coal have established that degradations or side reactions due to the K-CE-THF interactions is not significant. 17 to 20% THF solubles has been consistently obtained after K-CE treatment. A second K-CE treatment produced another 20% THF solubles. IR and TGA seemed to indicate that the same type of THF soluble fragments were released during both treatments. Work is currently being done using a well characterized coal sample from the Illinois Basin coal sample program. Thermal analysis of the coal extracts and residues from the coal-K-CE reaction were performed. 8 figs., 5 tabs.
