摘要：There are disclosed a process for producing a dihydric phenol which comprisesoxidizing a monohydric phenol by a peroxide compound in the presence of a β-zeolite, aketone and a phosphoric acid, and a process for producing a dihydric phenol whichcomprises oxidizing a monohydric phenol in the presence of a β-zeolite, a ketone and aphosphoric acid, by feeding a monohydric phenol, hydrogen peroxide, a ketone and aphosphoric acid into a reactor in which a β-zeolite is charged, to oxidize the monohydricphenol into a dihydric phenol, and delivering the resultant reaction mixture from thereactor.
