摘要： A process for the production of bisphenol A from phenol and acetone, comprises introducing a substantially anhydrous reaction mixture of phenol, acetone, and recycled solution of bisphenol A and reaction by-products in phenol into a reaction zone containing a cation-exchange resin catalyst, such catalyst being a mixture of resin having a macroporous structure and resin having a microporous structure in a ratio of 0.05:1 to 0.5:1 by weight, the mol ratio of phenol to acetone being 5:1 to 30:1, and the concentration of bisphenol A being 12 to 20% by weight. The temperature of the reaction zone is maintained between 60 degrees and 95 degrees C. The resulting reacted reaction mixture is withdrawn from the reaction zone, the concentration of bisphenol A being 21 to 35% by weight and the amount of reaction by-products being 12 to 24% by weight. Such withdrawn reaction mixture is treated to recover bisphenol A product and to provide the recycled solution of bisphenol A and reaction by-products in phenol.
