<p>PROBLEM TO BE SOLVED: To provide a method capable of efficiently producing a polyvalent glycidyl compound in which a side reaction such as hydrolysis of a glycidyl ether group originally present in a compound, gelation caused by hydrolysis and the like are suppressed when oxidizing a 2-alkenyl group of a glycidyl ether compound having a 2-alkenyl group by using a hydrogen peroxide aqueous solution as an oxidant.SOLUTION: There is provided a method for producing a polyvalent glycidyl compound by controlling a pH of a reaction solution containing a glycidyl ether compound having one or more substituted or unsubstituted glycidyl ether groups and two or more substituted or unsubstituted 2-alkenyl groups in the molecule to 1.0 to 4.0 in the presence of a tungsten compound as a catalyst, two or more acids containing at least phosphoric acid and a quaternary ammonium salt using a hydrogen peroxide aqueous solution as an oxidant, adding a hydrogen peroxide aqueous solution to the reaction solution over 0.1 to 2 hours, and after the completion of addition of the hydrogen peroxide aqueous solution, terminating the reaction for 2 to 6 hours.</p> |
