| 20110112333 | BPA PROCESS IMPROVEMENT - 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. | 05-12-2011 |
