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.
