Process for producing mixture of dihydroxydiphenylsulfone isomers |
| abstract |
It is intended to provide a process for producing a mixture of 4,4’- and 2,4’-dihydroxydiphenylsulfone isomers characterized in that trihydroxytriphenyldisulfone or a mixture of dihydroxydiphenylsulfone isomers containing trihydroxytriphenyldisulfone is heated in the presence of phenol and an acid catalyst. |
