    • The present invention provides a process for producing bisphenol A which is capable of prolonging the life of an acid-type ion exchange resin partially modified with a sulfur-containing amine compound as catalyst, and increasing the yield of bisphenol A per unit quantity of the catalyst. There is disclosed a process for producing bisphenol A by reacting acetone with phenol in the presence of an acid-type ion exchange resin partially modified with a sulfur-containing amine compound as catalyst and alkylmercaptan as co-catalyst, said process comprising:

      conducting said reaction using a multi-stage reaction apparatus comprising at least two individual reactors connected in series to each other, wherein the molar ratio of total alkylmercaptan to total acetone and the molar ratio of total acetone to phenol are increased as the conversion rate of the phenol is decreased.
    • 本发明提供一种能够延长用含硫胺化合物作为催化剂部分改性的酸型离子交换树脂的寿命并且提高每单位量催化剂的双酚A的产率的双酚A的生产方法 。 公开了一种通过丙酮与苯酚在用含硫胺化合物作为催化剂和烷基硫醇作为助催化剂部分改性的酸型离子交换树脂存在下反应生产双酚A的方法,所述方法包括:将所述反应 使用包含至少两个彼此串联连接的单独反应器的多级反应设备,其中随着苯酚的转化率降低,总烷基硫醇与总丙酮的摩尔比和总丙酮与苯酚的摩尔比增加 。
