METHOD FOR PRODUCING EPOXY RESIN, EPOXY RESIN, CURABLE RESIN COMPOSITION, AND CURED PRODUCT

摘要

The objective of the present invention is to provide a method for producing an epoxy resin, the method being capable of efficiently converting a carbon-carbon double bond of an allyl group of a specific allyl ether compound to an epoxy group, in other words, the method having a high yield of epoxy groups. This method for producing an epoxy resin comprises a step of reacting a compound represented by formula (I) (In the formula, n is an average value of the number of repetitions of 1 to 20) and a hydrogen peroxide in the presence of a tungstic acid compound, a quarternary ammonium salt, a cation exchange resin and a phosphate compound.
