Versuchsvorschrift

According to yet another preferred embodiment of the present invention, a process for producing bisphenol-A is provided, comprising reacting acetone and phenol to form a reaction mixture containing bisphenol-A and water, cooling the remainder of the reaction mixture to form bisphenol-A -phenol adduct crystals, separating the adduct crystals from the mother liquor, and removing phenol from the adduct crystals to obtain bisphenol-A, characterized in that the reaction of acetone and phenol is conducted in a reactor column having a plurality of perforated trays supporting a solid particulate catalyst, and an inert gas is passed upward through the reactor column during reaction in order to agitate the catalyst while stripping the water from the reaction mixture, thereby forming a reaction mixture effluent having a reduced water content.
