Zusammenfassung:PROBLEM TO BE SOLVED: To provide a method of preserving a catalyst which can keep an olefin oxide selectivity after its preservation for a long period of time. SOLUTION: In this method, the olefin oxidation catalyst, in which active components including silver and an alkali metal are supported on a carrier, is preserved at ≤30% relative humidity.
