A process for the production of a bisphenol compound comprising:a step for reacting a phenolic compound (a) with at least one compound (b) selected from the group consisting of dialkenylbenzene compounds, bis(hydroxyalkyl)benzene compounds and (hydroxyalkyl)-alkenylbenzene compounds or at least one compound (c) selected from the group consisting of monoalkenylphenolic compounds and mono(hydroxyalkyl)phenolic compounds in the presence of an acidic catalyst to obtain a reaction mixture containing said bisphenol compound,a step for neutralizing the reaction mixture with an anion exchange resin,a step for removing a remaining phenolic compound from the reaction mixture to concentrate the neutralized reaction mixture, anda step for isolating the bisphenol compound from the resulting concentrated mixture.This process enables to produce a bisphenol compound, which is useful for preparing raw materials of thermoplastic polymers, surface-active agents and stabilizers.
