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 60ยฐC. The principal products were 'black acids', insoluble in water but sparingly soluble in dilute aqueous base; small pr
