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

This paper summarizes efforts to increase the solubilities of coal fractions, with minimum loss of carbon, by oxidations with aqueous NaOCI, oxygen, and nitric acid, at or below 60°C. The principal products were 'black acids', insoluble in water but sparingly soluble in dilute aqueous base; small pr

In order to ascertain the composition differences between extracting by column-chromatography (CC) and by the Soxhlet method, and to look for an economically-friendly solid-sample-extraction method, three coal samples A, B and C were extracted by pyridine solvent at 25°C and 120°C by these two metho

When Illinois No. 6 whole coal or vitrain is extracted with pyridine14C, the extracts and solid residues retain 12-20% and 9-l 6%, respectively (at temperatures of 23 and 130°C) of the pyridine-14C. Repeated treatment of the extracts with benzene, followed by filtration and drying at 0.1 Pa for 48 h
