| titleOfInvention | Method for producing 2,4'-dihydroxydiphenyl sulfone |
| abstract | [PROBLEMS] To obtain 2,4′-dihydroxydiphenyl sulfone in a high yield by using phenol and phenolsulfonic acid, or phenol and sulfuric acid, fuming sulfuric acid or sulfuric anhydride as raw materials. A method for producing '-dihydroxydiphenyl sulfone is provided. In producing 2,4′-dihydroxydiphenyl sulfone by a dehydration condensation reaction using phenol and phenolsulfonic acid or phenol and sulfuric acid, fuming sulfuric acid or sulfuric anhydride as raw materials, the raw materials are 4,4′- A process for producing 2,4'-dihydroxydiphenyl sulfone, which comprises adding dihydroxydiphenyl sulfone. |
