Abstract

PURPOSE: To prepare high purity hydroquinone in high yield without using excess acid, by the hydrogen reduction of nitrobenzene in an aqueous solution of hydrogen halide in the presence of a reduction catalyst, followed by the hydrolysis of the resulting intermediate by heating without separating from the reaction mixture.
