摘要： PURPOSE: To obtain a compound useful as a substitute for bisphenol A in a short time in high yield, by reacting phenol with a sulfonating agent in the presence of a compound selected from Zn compound, Fe compound and Mg compound.
CONSTITUTION: Phenol is reacted with a sulfonating agent (e.g., conc. sulfuric acid, fuming sulfuric acid, sulfuric anhydride, etc.) or phenolsulfonic acid, to give dihydroxydiphenylsulfone. In the reaction, at least one compound selected from the group consisting of zinc compound, iron compound, magnesium compound, boron compound, and phosphorus compound (e.g., halide, sulfide, oxide, hydroxide, etc. of Zn) as a catalyst is added to the reaction system. A condensation reaction through dehydration is not preceded substantially when the reaction temperature is below 140°C, and side reactions occur actively when the reaction temperature is ≥250°C. The use of the catalyst reduces the content of by-products and precedes the condensation reaction through dehydration.

摘要： PURPOSE: To obtain a compound useful as a substitute for bisphenol A in high purity and in high yield, by using a mixed solvent of an alcohol and o-dichlorobenzene in a specific ratio from a mixture of dihydroxydiphenylsulfone isomers.
CONSTITUTION: 4,4'-Dihydroxydiphenylsulfone is isolated from a mixture of isomers of 4,4'-dihydroxydiphenylsulfone and 2,4'-dihydroxydiphenylsulfone. The mixture of the isomers is treated with a mixed solvent comprising 1W10wt% one or more alcohols selected from the group consisting of methanol, ethanol, n-propanol, and iso-propanol and 99W90wt% o-dichlorobenzene so that the isomers are separated. The separation is carried out by using a relatively inexpensive and industrially sufficiently usable solvent, and the operation in separation and purification is simple. The separation is done at room temperature so that it is industrially advantageous.
