Identification and cleavage of breakable single bonds by selective oxidation, reduction, and hydrolysis. Quarterly report No. 4, July 1-September 30, 1979
Bituminous coal is assumed to consist mostly of an aggregate of condensed aromatic and aliphatic rings, connected and made insoluble (but swellable) by crosslinks containing only single bonds. The object of this project is to determine the proportions of the various kinds of connecting links and how they can be broken - in other words, to determine the structure of coal, with emphasis on the crosslinks and breakable single bonds. We have made considerable progress in breaking down coal below 100/sup 0/, mostly with mild reagents. We have increased the solubility of the orginal coal in solvents, compared semiquantitatively the abilities of several agents to cleave asphaltols, probably at ether links, and made large proportions of both extracted coal and asphaltol soluble in weakly basic water solution by oxidation. Oxidations of asphaltol in water suspension with oxygen and NaOCl have been carried out recently, with good conversions and yields of black acids. 4 references, 3 figures, 5 tables.
