Bisphenol composition containing aromatic alcohol sulfonate and method for producing same, polycarbonate resin and method for producing same, and bisphenol production method
2018
Disclosed is a bisphenol composition containing a specific amount of an aromatic alcohol sulfonate, and a simple method for producing the same. Further, by using a bisphenol composition containing a specific amount of the above-mentioned aromatic alcohol sulfonate, a melt polymerization reaction can be efficiently advanced to provide a method for producing a polycarbonate resin capable of producing a polycarbonate resin excellent in color tone. . A bisphenol composition containing 0.1 mass ppb or more of an aromatic alcohol sulfonate relative to bisphenol. Also, a method for producing a bisphenol composition, which comprises reacting the ketone or aldehyde with an aromatic alcohol in the presence of sulfuric acid to produce the bisphenol composition. Moreover, the manufacturing method of polycarbonate resin which manufactures polycarbonate resin using the said bisphenol composition. In addition, polycarbonate resin containing a specific amount of aromatic alcohol sulfonate.
