PROCESS FOR STABILIZING A LIQUID CRUDE BISPHENOL A PRODUCT STREAM |
摘要 |
<p>Product losses and color formation are sometimes encountered in the synthesis of bisphenol A from phenol and acetone in the presence of a cation exchange resin, particularly in the crude product stream from which bisphenol A has been separated via its phenol adduct. Such losses are suppressed and the crude product stream stabilized and decolorized by contact with an anion exchange resin.</p> |
