When the middle oils obtained from the hydrogenation of coal were hydrogenated at 450" and 475" c. in a stainless-steel autocIave in the absence of any added catalyst, very IittIe of the phenolic material was convened to neutral products. Whereas the original material contained only 2.9";, phenols boiling below 230' c., the hydrogenated product (at 475"c.) contained 9.1"/, (based on the charge) phenols boiling below this temperature. When the phenolic fraction of the middle oil was isolated before hydrogenolysis and then treated, more conversion of high-boiling to low-boiling phenols occurred, but this was accompanied by elimination of oxygen and the production of about 2oU,, neutral material.
