It was established that selective O-alkylation changes the density and petrography of two bituminous coals. The extent of the change depends upon the character of the alkyl group added to the coal. Reductions, reductive alkylation and alkylation reactions were carried out on PSOC-1197. Reduction reactions were carried out on PSOC-619, 726 and a Texas lignite. The solubilities in pyridine, dimethyl sulfoxide and tetrahydrofuran of the reaction products are presented. The results suggest the use of elemental analysis and spectroscopic studies along with solubilities for the measure of degree of reduction. 11 references, 7 figures, 6 tables.
