CATALYST FOR BISPHENOL PRODUCTION

摘要

A catalyst for bisphenol production which can be prepared by a simple procedure using a sulfurized amine compound which is contained in a wastewater discharged from a bisphenol production process and should be removed from the wastewater; and a process for producing a bisphenol with the catalyst. The catalyst for bisphenol production is obtained by causing a sulfurized amine compound contained in a wastewater discharged from a bisphenol production process to be adsorbed onto an acid cation-exchange resin. ® KIPO & WIPO 2007
