| titleOfInvention | Method for producing bisphenol S alkylene oxide adduct |
| abstract | Kind Code: A1 Abstract: A ring-opening addition reaction of an alkylene oxide to bisphenol S has a small loss of an alkylene oxide, and a bisphenol S alkylene oxide adduct, particularly a bisphenol S alkylene oxide 2 mol adduct is obtained with high selectivity and high yield. To provide a manufacturing method. A method for producing a bisphenol S alkylene oxide adduct, comprising reacting bisphenol S with an alkylene oxide in the presence of an alkali catalyst using a glycol ether having a specific structure as a solvent. Further, a method for producing a high-purity bisphenol S ethylene oxide adduct in which the bisphenol S ethylene oxide adduct is purified by recrystallization in the same solvent.
