  • Process for the thermal after-treatment of cleavage prodcuct from the acid-catalyzed cleavage of cumene hydroperoxide
    Publication number: 20010039362
    Abstract: The cleavage product from the acid-catalyzed cleavage of cumene hydroperoxide into phenol and acetone is subjected to thermal after-treatment by a process, which comprises heating the cleavage product in a reactor, wherein the heat supplied for the thermal treatment is the heat generated by at least one exothermic reaction which occurs in the reactor. The exothermic reaction which proceeds in the cleavage product is preferably the cleavage of cumene hydroperoxide.
