摘要： An improved process for recovering phenol from a bisphenol-A residue stream by reconfiguring the distillation column and the cracking reactor in a way that separates the reboil/distillation heat load and the cracking heat load, so that separate heat sources are used.

摘要： In a method of treating a residue stream from the production of bisphenol-A, the residue stream is contacted with an aqueous solution of a base under conditions effective to hydrolyze at least part of said residue stream into acetone and phenol and produce an effluent stream. Acetone is recovered from the effluent stream to produce a phenol-containing mixed phase stream which is substantially free of acetone and which contains water and unhydrolyzed heavy organic compounds. The phenol-containing mixed phase stream is then treated with a water-immiscible organic solvent to extract phenol and unhydrolyzed heavy organic compounds into said solvent and produce an organic phase containing the solvent, phenol and unhydrolyzed heavy aromatic compounds and an aqueous phase with reduced concentrations of phenol and unhydrolyzed heavy organic compounds. At least part of the phenol and the organic solvent are subsequently recovered from the organic phase.

摘要： In a method of recovering phenol and acetone from a feed stream containing bisphenol-A and isomers thereof, the feed stream is contacted with water and a source of hydroxyl ions under conditions effective to decompose at least part of said bisphenol-A and isomers thereof to phenol and acetone. The conditions include a temperature of 150 C to 300 C, a pressure sufficient to keep the water substantially in the liquid phase at said temperature, and a molar ratio of hydroxyl ions to hydroxyphenyl groups in the residue stream from 0.3:1 to 0.9:1.
