Title: Identification and cleavage of breakable single bonds by selective oxidation, reduction, and hydrolysis. Quarterly report No. 6, January 1-March 31, 1980

Technical Report ·
OSTI ID:6169459

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 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 bond. This report summarizes progress during the past quarter of the following tasks: (1) cleavages and alkylations of pyridine TIPS 28-A which covers treatment with zinc chloride in THF, alkylation, fractionation with KOH/ETOH, and solubilization with KOH in toluene; (2) cleavages of pyridine-extracted coal 18-A which includes pyridine hydroiodide in pyridine, zinc chloride in THF; (3) cleavage of pyridine-extracted coal with phenol and p-toluene sulfonic acid; (4) oxidation of pyridine-extracted coal with nitric acid; and (5) cleavages of benzylamine extraction products. 5 references, 2 figures, 4 tables.
