摘要:A crystalline adduct of bisphenol A and phenol is produced by crystallization ofa phenolic slurry of bisphenol A. The crystallization of the slurry is performed bycontinuously discharging a portion of the slurry from the crystallization zone into aplurality of cooling zones and then recycling the cooled slurry to the crystallization zone.The cooling zones are connected in parallel and they are operated so that at any onetime one of the cooling zones can be cleaned of deposits of crystalline adduct withoutstopping the process. An apparatus having a plurality of coolers and suitable foreffecting the above crystallization process is also disclosed.
