    摘要: Aminobenzenes (e.g., aniline) are converted to the corresponding hydroxybenzene by reaction with water in the presence of a hydrogen transfer catalyst (e.g., palladium) and a reaction propagating agent selected from cyclohexanones and cyclohexylimines. The cyclohexylimine may be formed by initially adding a reducing agent (e.g., hydrogen) to the aminobenzene.

    摘要: Resorcinol is produced by the hydrolysis of metaphenylenediamine in an aqueous excess of ammonium bisulfate. The reactants are contacted at an elevated temperature for a period of time sufficient to hydrolyze the meta-phenylenediamine to resorcinol. The resorcinol so produced is separated from the reaction mixture. The ammonium sulfate is regenerated to ammonium bisulfate by removing the water and thermally decomposing the byproduct ammonium sulfate at an elevated temperature.
