This Paper presents a statistical and mathematical analysis of hypotheses concerning the autoclave hydrogenating depolymerization of coal extract fractions insoluble in benzene. From comparison of theoretical and experimental data the most probable reaction mechanism was selected.
Fourier-transform infrared spectroscopy offers considerable advantages over conventional dispersive methods for the characterization of highly absorbing materials such as coal. This technique has been applied to the determination of the functional groups present in three solvent-refined-coal samples
The toluene-insoluble, pyridine-soluble (TIPS) fractions of an Illinois No. 6 coal were investigated as a model for the insoluble portion of coal. Various TIPS fractions had number-average molecular weights (iii,) in pyridine of 9080 to 1380. These fractions were treated with a variety of reagents k
