发明名称 Process for the preparation of bisphenols
摘要 <p>A process of 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, and a 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.</p>
