ABSTRACT:
High quality hydroquinone is produced from p-diisopropylbenzene dihydroperoxide at a high yield according to the disclosed process. The p-diisopropylbenzene dihydroperoxide is decomposed in the presence of an acid catalyst and the concentration of the hydroperoxide is maintained in the range of 0.1 to 1% by weight; the remaining hydroperoxide in the decomposition step is further subjected to an acid decomposition prior to the recovery of the formed hydroquinone product.
