日本Mitsubishi化学公司开发了一种更有效的催化剂，使用该催化剂改善了双酚A（BPA）的生产工艺。Mitsubishi公司自１９９７年起就在Kashima一套７０kt／a的设备中采用CT－BISA工艺。该工厂使用一种阳离子交换树脂催化剂，在低于１００℃和大气压下，在填充床反应器中用丙酮和
Japan’s Mitsubishi Chemical Company has developed a more effective catalyst, using the catalyst to improve the production process of bisphenol A (BPA). Mitsubishi has been using the CT-BISA process in a 70 kt / a Kashima unit since 1997. The plant uses a cation exchange resin catalyst at below 100 ° C and atmospheric pressure in a packed bed reactor with acetone and
