Certain high-sulphur-containing, high-volatile bituminous (hvb) coals have been converted into products which are almost completely soluble in chloroform. These products were obtained by a series of reactions involving initial oxidation with 2N nitric acid, depolymerization with boron trifluoride-ph

The depolymerization reaction of coal in the presence of Friedel-Crafts catalysts in a variety of phenolic and non-phenolic solvents has been investigated. Only the phenoiic solvents were found to be useful in this reaction. Some interesting substituent effects were discovered when the isomeric cres
Hg). Soxhlet extraction of the residue with pyridine was followed by evaporation of the pyridine extracts as described above. The amount of coal converted to a pyridinesoluble product by the heat/tetralin treatment was 97% on a maf basis. The composition of the pyridine-soluble conversion product in
