EPOXIDATION CATALYST, PROCESS FOR PRODUCTION OF EPOXIDATION CATALYST, PROCESS FOR PRODUCTION OF EPOXY COMPOUNDS, CURABLE RESIN COMPOSITIONS, AND PRODUCTS OF CURING OF THE COMPOSITIONS

摘要

The invention provides an epoxidation catalyst which exhibits high activity and excellent selectivity for a target compound. An epoxidation catalyst for the oxidation of polyvalent alkenes into epoxy compounds which consists of a peroxide derived from a tungstic acid, characterized by having a characteristic absorption at 815 to 825cm-1 in the infrared absorption spectrum.
