METHOD FOR PRODUCING BISPHENOL-A |
摘要 |
Provided is a process for producing a bisphenol A by continuously feeding phenol and acetone into a reactor unit having at least two reaction zones connected in series. In the process, an acidic cation-exchange resin partially neutralized with a sulfur-containing nitrogen compound in from 15 to 50% of the acid site thereof is used as the catalyst, and acetone having a methanol concentration of at most 3,000 ppm is separately fed into at least two reaction zones in the reactor unit. The life of the acidic cation-exchange resin catalyst used in the process is prolonged. |
