| titleOfInvention | Method of producing bisphenol and method of producing polycarbonate resin |
| abstract | PROBLEM TO BE SOLVED: To produce a bisphenol having a good color tone by shortening the reaction time to a bisphenol, improving the selectivity of the bisphenol to be produced, in the reaction of producing a bisphenol from an aromatic alcohol and a ketone or an aldehyde I will provide a. SOLUTION: In a state of oil-water separation into an organic phase containing an aromatic alcohol and an aqueous phase containing sulfuric acid, an aromatic alcohol sulfonic acid is formed in the organic phase, and a reaction product liquid containing the aromatic alcohol sulfonic acid is obtained. And a reaction product liquid containing the aromatic alcohol sulfonic acid and a ketone or an aldehyde, and the aromatic alcohol and the ketone or aldehyde are mixed in the presence of the aromatic alcohol sulfonic acid. And (2) producing a bisphenol. [Selected figure] None |
