Abstract
In order to produce an epoxy compound with a less chlorine content at a higher reaction rate and yield, the present invention provides a method for producing an epoxy compound by reacting a compound having a carbon-carbon double bond with hydrogen peroxide in the coexistence of the compound having a carbon-carbon double bond, the hydrogen peroxide solution, a powdered solid catalyst support and a powdered solid catalyst all together, the solid catalyst comprising isopolyacids produced from (a) tungstic acid or a salt thereof and (b) a quaternary ammonium salt compound and/or a pyridinium salt, selected from halogen-free compounds.
