- PROCESS FOR PRODUCTION OF EPOXY COMPOUND
-
A novel process for producing a polyfunctional epoxy monomer is provided that facilitates separation of an aqueous layer catalyst from a reaction solution and has satisfactory hydrogen peroxide efficiency by reacting an aqueous hydrogen peroxide solution with a polyolefin without using an organic solvent and under mild conditions. The process as claimed in the present invention is a process for producing a corresponding epoxy compound by reacting an organic compound having a carbon-carbon double bond with hydrogen peroxide present in an aqueous hydrogen peroxide solution to epoxidate the double bond, wherein a tungsten compound and tertiary amine are used as reaction catalysts.
