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.
一种生产双酚化合物的工艺,包括
第一步: 在酸性催化剂存在下,将酚类化合物(a)与至少一种选自二烯基苯化合物、双(羟基烷基)苯化合物和(羟基烷基)-烯基苯化合物或至少一种选自单烯基酚类化合物和单(羟基烷基)酚类化合物的化合物(b)反应,得到含有所述双酚化合物的反应混合物、
用阴离子交换树脂中和反应混合物的步骤、
从反应混合物中去除剩余的酚类化合物以浓缩中和反应混合物的步骤,以及
从浓缩后的混合物中分离出双酚化合物的步骤。
该工艺可以生产出双酚化合物,这种化合物可用于制备热塑性聚合物的原料、表面活性剂和稳定剂。
