Abstract
[Problem] To provide a process for producing an aromatic dihydroxy compound, in which a hydroquinone compound is highly selectively produced while suppressing formation of by-products derived from a solvent and maintaining a high yield based on hydrogen peroxide when a phenol compound is allowed to react with hydrogen peroxide. [Solution] A process for producing an aromatic dihydroxy compound, including allowing a phenol compound to react with hydrogen peroxide in the presence of a titanosilicate, a C4-C5 alcohol containing a tertiary or quaternary carbon, and water and/or methanol, the amount of the water and/or methanol being 5 to 90 mass % based on the total mass of the reaction liquid.
