摘要 A new process for the preparation of a mixture of pyrocathechin and hydroquinone prevailingly consisting of pyrocatechin, by direct hydroxylation of phenol with hydrogen peroxide. The novelty resides in the use of ferrocene or a derivative thereof as the catalyst. A better control of the reaction, higher yield and an easier final separation are achieved.
