Abstract

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 bonds. This report presents brief summaries and experimental details of the following tasks; acetylation of asphaltols and black acids; cleavages of asphatol 28-A; cleavages of benzylamine extraction products; investigations of black acids; oxidation and oxidation products of coal extracts and black acids; and gel permeation chromatography. 6 references, 1 figure, 5 tables.

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 themore »« less

Technical Report Buchanan, D; Mayo, F

The objective of this project is to determine the structure of bituminous coal with emphasis on the crosslinks and breakable single bonds. During this past quarter, a new gel permeation chromatography system using pyridine as solvent was installed and calibrated. Pyridine dissolved some coal fractions that were only partly soluble in tetrahydrofuran, but the sensitivity of the detector was lower with pyridine because its index of refraction was closer to that of coal products. Acetylation, methylation, trimethylsilylation, and decyldimethylsilylation of the pyridine soluble, toluene-insoluble (asphaltol) fraction of Illinois No. 6 coal extract and of products obtained from that extract weremore »« less

We assume that bituminous coal consists mostly of an aggregate of condensed aromatic and aliphatic rings, connected and made insoluble (but swellable) by crosslinks containing 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 bituminous coal, with emphasis on the crosslinks and breakable single bonds.
