The distribution of functional groups in low rank coals has been the subject of a body of investigations (summarized by Meyers (1982) and Spiro and Kosky (1982)) oriented towards a description of the kinetics and mechanism of thermal conversion processes. Use of the new technique of Californium-252 Plasma Desorption Mass Spectrometry (CFPDMS) as a probe to the structural features of coal have been described by Lytle, Tingey and Macfarlane (1982). The interpretation of CFPDMS spectra has necessitated a a functional group characterization of the coal substrate by conventional spectroscopic and chemical techniques. CFPDMS requires the use of organic soluble fractions, and we have utilized DMSO extracts as they seem quite representative of the organic functionalities present. Dry Wilcox Lignite (WL) and some of its solubility fractions have been so characterized, including its DMSO solubles (SD), DMSO insolubles (ID), humic acids (HA), a sample demineralized (DM) by the method of Bishop and Ward (1958), the DMSO extract of this (SDM), and the insoluble residue (IDM).
