Abstract
Provided is a safe and simple method for producing an epoxy compound, wherein a compound with a carbon-carbon double bond is epoxidized by using hydrogen peroxide as an oxidizing agent in the presence of acetonitrile, wherein there is no need for concentration of a reaction mixture that contains residual hydrogen peroxide. A method for producing an epoxy compound wherein a compound with a carbon-carbon double bond is epoxidized by using hydrogen peroxide as an oxidizing agent, in the presence of acetonitrile, comprises a first step of adding water and an organic solvent that is incompatible with water and does not dissolve an acetamide by-product of the epoxidation reaction to a reaction mixture, upon completion of the epoxidation reaction, to dissolve the acetamide in the water, a second step of separating an organic layer and an aqueous layer, and a third step of subjecting the organic layer to reduction treatment, and then rinsing and concentrating it to provide an epoxy compound.
