摘要： A method for producing 3,3’-diallyl-4,4’-dihydroxydiphenylsulfone, which comprises subjecting 4,4’-diallyloxydiphenylsulfone to a rearrangement reaction under the irradiation with a microwave, preferably in a molten state, more preferably further in a substantially oxygen-free atmosphere and in the presence of at least one compound selected from the group consisting of an antioxidant, an organic base compound and a chelate compound. The method allows the production of the objective compound having a high purity with good efficiency in a short time in good yield.

摘要： Disclosed is a microwave chemical reaction apparatus comprising a means for heating a reaction solution, which is capable of irradiating the reaction solution with microwaves while controlling the output power according to the temperature of the reaction solution, and a means for forcibly cooling the reaction solution on the outside. The microwave chemical reaction apparatus is characterized by being capable of precisely controlling the reaction temperature. In this microwave chemical reaction apparatus, the reaction temperature can be controlled precisely, for example, within ±1˚C of a predetermined temperature, and thus this apparatus can be applied to precise chemical reactions. Since reactions proceed rapidly in such an apparatus, mass production can be achieved by a relatively small-sized reaction apparatus.
