Aliphatic components of coal. Quarterly report for the period September-December 1979

TL;DRAbstract

The elucidation of the structures of coals and coal-derived liquids continues to be a challenging problem on which we are making much progress. Our contributions are somewhat unique at this point in time because of (a) the development of a new method for chemical clevage of coals, (b) the application of our excellent gas chromatography-mass spectroscopy interfacing to previous methods of chemically cleaving coals, and (c) the coupling of these methods to arrive at a coherent view of coal structure. It should be evident that although spectroscopic studies of coals are of great importance, they tend to yield averaged properties and averaged structures. To fully define the structure of coals, they must be chemically cleaved to fragments whose structure can be totally determined. If chemical clevage of coals has been disappointing in the past, it only emphasizes the need for developing cleverer ways of chemically cleaving the coals.
