The concentration of 20 weight 0 / o is less than the bisphenol A low recovery rates, it is difficult to transfer the slurry of the after crystallization exceeds 50% by weight. Process (4) (crystallization process)
- the concentrated residue obtained in the step (3) is cooled to 40 to 70 ° C., and an adduct of bisphenol A and phenol (hereinafter abbreviated as phenol adduct) crystallizes to form a slurry. Cooling is performed by heat removal by evaporation of water added to the external heat exchanger / crystallizer.
