Previous work showed that the eff icient 'depolymerization'of bituminous coals in hot phenol containing p-toluenesulphonic acid failed to occur and that the acid was destroyed during the reaction. Four coals varying in rank from lignite to low volatile bituminous were treated with refluxing phenol c

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
