Bisphenol-A plant yield enhancement

An improved process is provided for producing bisphenol-A (BPA) comprising steps of (1) contacting benzene and a C3 alkylating agent to produce an alkylation effluent comprising cumene; (2) oxidizing the cumene to produce the corresponding hydroperoxide; (3) cleaving the hydroperoxide to produce product comprising phenol and acetone; (4) reacting acetone with phenol to form a reaction product stream comprising crude bisphenol-A product; (5) distilling the reaction product stream, while sending downstream to a BPA-phenol adduct crystallization and purification step, the resulting concentrated BPA phenolic feed stream; (6) producing BPA-phenol adduct crystals by crystallization of the concentrated BPA phenolic feed stream; (7) separating the BPA-phenol adduct crystals by solid-liquid separationr; (8) cracking a stream comprising at least a portion of said final mother liquor to recover a product; and (9) recovering and feeding the phenol product of step (8) to step (4) and/or step (7).
