Development and Application of Analytical Techniques to Chemistry of Donor Solvent Liquefaction. Final Report, January 1, 1980-December 31, 1981

摘要

The scope of this project was to develop and apply analytical techniques for the characterization of coal conversion products. Solvent refined coal and process solvents derived therefrom served as the coal derived material for the duration of the study. The investigation has been focused primarily in the areas of inductively coupled plasma atomic emission spectrometry (ICP-AES) and nuclear magnetic resonance spectroscopy (NMR). Highlights of the twenty-four month study are: (1) Trace metal analyses of ashed SRC fractions via ICP-AES; (2) ICP-AES as a multielement detector in gel permeation chromatography; (3) GPC-ICP-AES applied to SRC fractions; (4) ICP-AES detection in normal phase chromatography; (5) LC- exp 1 H NMR applied to a high field NMR system; (6) LC- exp 1 H NMR analysis of coal recycle solvents; (7) Fluorine reagents examined for speciating heteroatoms in SRC; (8) Application of p-fluorobenzoyl chloride reagent to model samples; and (9) Application of the p-fluorobenzoyl chloride reagent to SRC fractions.
