Technology Introduction:

There are over 10 methods , and among them the prevailings are Aniline Oxidation Process, p-DIPB Excess Oxidation Process and Phenol Hydroxylation Process. Their comparisons are shown in the following table. SL TECH's technology is based on Phenol Hydroxylation Process, in which phenol feedstock reacts with hydrogen peroxide in presence of catalyst to yield o-dihyoxybenzene and p-dihyoxybenzene. After removing water, high boiling point substances, phenol and separating out o-dihydroxybenze, crude p-dihyoxybenze is obtained and then charged for dissolving, discoloring, recrystallization before getting hydroquinone product.
