実験手順
It is known to prepare 4,4'-dihydroxydiphenylsulfone from phenol and sulfuric acid. This process yields 4,4'-dihydroxydiphenylsulfone along with large quantities of 2,4'-dihydroxydiphenylsulfone as an isomer by-product. However, extreme difficulty is encountered in separating the 4,4'-dihydroxydiphenylsulfone directly from the resulting reaction mixture.
