ABSTRACT:
Occluded organic solvent is removed from bisphenol crystals by placing in water maintained at a temperature sufficient to form a molten water-bisphenol phase, holding at that temperature for a time sufficient to transfer the organic solvent to the water phase, flash distilling the organic solvent, cooling molten water-bisphenol phase to produce crystallization and thereafter recovering the bisphenol.
