| titleOfInvention | Method of producing bisphenol A |
| abstract | Provided is a method of producing bisphenol A in which the life of the acid-type ion-exchange resin used as a catalyst can be prolonged. The method comprises reacting phenol and acetone in the presence of an acid-type ion-exchange resin serving as a catalyst and an alkylmercaptan serving as a promoter to give bisphenol A, in which three or more reactors connected in series are used and all of phenol, all of an alkylmercaptan and a part of acetone are fed into the first reactor while the remaining acetone, divided into plural portions, is into all the second to the last reactors. |
