Process for preparing a bisphenol |
| abstract |
In a process for the preparation of a bisphenol by condensation of a phenolic compound and a carbonyl compound in the presence of an acidic ion exchange resin catalyst, strong acids that leach from the acidic ion exchange resin catalyst into the reaction effluent are scavenged by a carbon adsorbent. The acid scavenging improves the product quality and yield by reducing acid catalyzed cracking of bisphenols during purification and finishing steps. |
