  • Oxidizing fused ring compounds to quinones with aqueous acidic solutions of cerium
    申请人:DIAMOND SHAMROCK CORPORATION
    公开号:EP0075828A1
    公开(公告)日:1983-04-06
    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.
    本发明公开了一种高效经济的工艺,通过铈的酸性水溶液将熔融环烃氧化成醌。所采用的水溶液包括稀硝酸,其中铈的总含量约为每升 0.5 至 1.5 克原子,其中约 30% 至约 70% 但不少于每升约 0.2 克原子为四价态。上述酸性水溶液可以很容易地回收,并在具有商业吸引力的每平方英寸一安培或更高的电流密度下进行电解处理,以再生四价铈,用于氧化更多数量的熔环烃。
