Abstract: A system for purifying a cumene hydroperoxide cleavage product mixture comprises a cumene hydroperoxide cleavage product mixture feed containing impurities in fluid communication with an aqueous alkaline solution feed; the cumene hydroperoxide cleavage product mixture and aqueous alkaline solution feeds are in fluid communication with a neutralization drum having an aqueous salt phase outlet; an aqueous salt phase feed containing impurities in fluid communication with a heat treatment vessel having a heat-treated aqueous salt phase outlet; and a heat-treated aqueous salt phase feed containing water-soluble derivatives of the impurities in fluid communication with the cumene hydroperoxide cleavage product mixture prior to the neutralization drum.
