Identification and cleavage of breakable single bonds by selective oxidation, reduction, and hydrolysis. Quarterly report No. 7, April 1-June 30, 1980
The purpose is to determine the structure of bituminous coal with emphasis on the crosslinks and breakable single bonds. Most of our past cleavage efforts have been directed to the toluene-insoluble, pyridine-soluble (TIPS) fraction of pyridine-extracted coal itself. This report describes extensions of these investigations, as well as experiments with benzylamine extract and with benzylamine extracted coal. Many of our materials are not soluble enough in NMR solvents to give useful /sup 13/C NMR spectra, which are needed to follow changes in structure and composition. Efforts to increase the solubility of these fractions continue. Experimental details are presented for the following: (1) investigations of TIPS fraction of pyridine extract of coal; (2) cleavages and alkylations of pyridine-extracted coal; (3) fractionation of benzylamine extract 11-A; (4) oxidations of benzylamine-extracted coal; and (5) extractions of whole coal. 6 references, 1 figure, 3 tables.
