Abstract
PURPOSE: High quality hydroquinone is prepared with low cost by the reduction of nitobenzene in an aqueous strong acid solution to afford p-aminophenol, and without decomposing the aminophenol, the concentration of said acid is adjusted to a specific value thereby hydrolyzing said aminophenol.
