Identification of the heteroatom containing compounds in the benzene/methanol extracts of the Argonne Premium Coal Samples

摘要: The Argonne Premium Coal Samples (APCS) provide a unique opportunity to study set of pristine samples specifically selected represent the vast diversity chemical structures exhibited by US coals. purpose this paper is utilize high resolution mass spectrometry (HRMS) characterize heteroatom containing species that can be extracted from APCS. Of special interest change in structure and relative concentrations these compounds undergo with rank. resulting information important providing basic structural concerning coals which are being used significant portion coal community, understanding transformations during coalification process. 15 refs., 4 figs., 2 tabs.
