Abstract:
1. A method for producing an epoxy compound by reacting a compound having a carbon-carbon double bond with hydrogen peroxide, comprising carrying out repeatedly or continuously the following steps (1), (2) and (3): step (1) of reacting a compound having a carbon-carbon double bond with hydrogen peroxide in the coexistence of (a) the compound having a compound having a carbon-carbon double bond, (b) a hydrogen peroxide solution, (c) a powdered solid catalyst support and (d) a powdered solid catalyst and optionally further (e) an organic solvent to produce an epoxy compound; step (2) of separating the epoxy compound that is the reaction product from the reaction mixture produced in step 1; and step (3) of adding (d) the powdered solid catalyst and also adding (a) the compound having a carbon-carbon double bond, (b) the hydrogen peroxide solution, (c) the powdered solid catalyst support and optionally further (e) the organic solvent to the mixture of the powdered solid catalyst support and powdered solid catalyst after separating the reaction product in step (2) wherein the powdered solid catalyst is selected from the group consisting of isopolytungstic acids containing cetyltrimethylammonium as a cation and isopolytungstic acids containing (NH
