摘要： An efficient and economical process is disclosed for oxidizing fused ring hydrocarbons to quinones by means of an aqueous acidic solution of cerium. The aqueous solution employed comprises dilute nitric acid containing a total cerium content of between about 0.5 and about 1.5 gram atoms per liter, about 30% to about 70% of which but not less than about 0.2 gram atom per liter is in the tetravalent state. Said aqueous acidic solution can be easily recovered and electrolytically treated at commercially attractive current densities of one ampere per square inch or higher to regenerate tetravalent cerium for reuse in oxidizing additional quantities of fused ring hydrocarbon.
