Identification and cleavage of breakable single bonds by selective oxidation, reduction, and hydrolysis. Quarterly report No. 3, April 1-June 30, 1979
Bituminous coal is assumed to consist mostly of an aggregate of condensed aromatic aliphatic rings, connected and made insoluble (but swellable) by crosslinks containing only single bonds. The objective of this project is to determine the proportions of the various kinds of connecting links and how they can best be broken--in other words, to determine the structure of coal, with emphasis on the crosslinks and breakable single bonds. This report describes: (1) preparation of asphaltol from Illinois No. 6 coal; (2) fractionation of asphaltol with bases, benzyamine, 5% KOH in ethanol, and combination of these; (3) cleavages of asphaltol by methyl iodide, HI in pyridine solution, and trimethyliodosilane; (4) efforts to solubilize the black acids from NaOCl oxidation of extracted coal; (5) oxidation of extracted coal and asphaltol.
