The present disclosure enables phenol recovery, purification and recycle
in a simple, economic manner from waste streams from, for example, a
phenol/acetone production process, e.g., a phenol/acetone plant or an
upstream cumene hydroperoxide cleavage process step, and BPA production
step, for use in the reaction with acetone to produce BPA. The disclosure
therefore reduces the overall consumption of phenol in the production of
BPA.
