| titleOfInvention | Process for producing mixture of dihydroxydiphenylsulfone isomers |
| abstract | It is intended to provide a process for producing a mixture of dihydroxydiphenylsulfone isomers containing 2,4’-dihydroxydiphenylsulfone characterized in that 4,4’-dihydroxydiphenylsulfone or a mixture of dihydroxydiphenylsulfone isomers containing 85% by weight or more of 4,4’-dihydroxydiphenylsuflone is heated in the presence of phenol and sulfuric acid, or in the presence of phenol and sulfonic acid. |
