Abstract
PURPOSE: To prepare a 2, 2'-bisphenolsulfone derivative useful as a light stabilizer, etc. in high yield, by oxidizing a 2, 2'-bisphenolsulfoxide with hydrogen peroxide in water and/or an organic solvent which does not form organic peracids, in the presence of a more than equimolar amount of alkali.
CONSTITUTION: A 2, 2'-bisphenolsulfone derivative is efficiently prepared from a 2, 2'-bisphenolsulfoxide. The reaction is carried out by oxidizing the starting material with hydrogen peroxide in the presence of an alkali, e.g. one to five times mole of NaOH, etc. The solvent is water and/or an organic solvent which does not form organic peracids with hydrogen peroxide. A solvent which is immiscible with water, e.g. benzene, carbon tetrachloride, etc., is advantageously used because it can be recovered by steam distillation after the reaction.
EFFECT: A highly pure product is obtained without the problem of the waste water treatment.
USE: Modifiers for polyolefins, etc.
