METHOD OF REDUCING METHANOL IN RECYCLE STREAMS IN BISPHENOL-A-PRODUCTION PROCESS

摘要

Methods for removing methanol from acetone recycle streams during bisphenol-A production, thereby avoiding the deactivation of catalyst, by distilling an acetone-methanol- water comprising mixture such that acetone is taken overhead in form of a relatively pure distillate, and substantial portions of the methanol and the water are leaving with the bottom product.
