METHOD FOR PRODUCING TUNGSTEN PEROXIDE COMPOUND, AND METHOD FOR PRODUCING EPOXY COMPOUND

WIPO Patent Application WO/2013/133009

A1

As a novel method for producing a tungsten peroxide compound useful as a catalyst for the epoxidation of an alkene, a method for producing a tungsten peroxide compound is provided which is characterized by comprising reacting (a) tungstic acid with (b) an ammonium hydroxide compound selected from (H4N)(OH), (H3R1N)(OH), (H2R1R2)(OH), (HR1R2R3N)(OH) and (R1R2R3R4N)(OH). Also provided is a method for producing an epoxy compound using the catalyst. (In the formulae, R1 to R4 may be the same as or different from one another, independently represent a linear or branched alkyl group having 1 to 18 carbon atoms, a cycloalkyl group or a benzyl group, and may contain nitrogen or oxygen.)
