Reactions governing coal solubilization. Tenth quarterly report, October 15, 1985-January 15, 1986
PSOC-1197 has been reduced with large quantities of potassium in ND/sub 3/ and quenched with ND/sub 4/Cl with the purpose of characterizing the sites of reactions. The deuterium NMR spectrum of the pyridine soluble product suggests cleavage of carbon-carbon bonds and some degree of disproportionation of hydroaromatic structures either native to the coal or formed in the reduction reactions. Results of alkylation and various other reactions of PSOC-1197 in a strongly basic medium suggest that the small degree of alkylation is largely responsible for the high extractability. Effects of various alkylation and reduction reactions on Texas lignite are also described. 17 refs., 4 figs., 3 tabs.
