| titleOfInvention | Method for producing 4-substituted hydroxy-4'-hydroxydiphenyl sulfone |
| abstract | (57) Abstract: Colorless, high-purity 4-substituted hydroxy- Provided is a method for industrially advantageously producing 4′-hydroxydiphenyl sulfone. A compound represented by the formula (II) and a compound represented by the formula (III): A method for producing a compound represented by the formula (I), comprising: a reaction step of reacting a compound represented by the formula in a solvent in the presence of a base; and a purification step of purifying the obtained reaction mixture, A method for producing a compound represented by the formula (I), further comprising a removing step of removing an unreacted compound represented by the formula (III) from the reaction mixture. Embedded image (Wherein, R 1 and R 2 represent a halogen atom, a C1-C8 alkyl group or a C2-C8 alkenyl group, m and n each represent an integer of 0 or 1-4, and R 3 represents Represents an 8 alkyl group, a C2-8 alkenyl group, a C3-8 cycloalkyl group or an aralkyl group which may have a substituent, and X represents a halogen atom. ) |
