ABSTRACT:
A process for producing an olefin oxide comprising oxidizing a corresponding lower olefin with molecular oxygen in the gas phase in the presence of a crystalline metallosilicate having supported thereon at least one salt selected from the group consisting of alkali metal salts of nitric acid, alkaline earth metal salts of nitric acid, silver salts of nitric acid and silver salts of nitrous acid. Said process can produce an olefin oxide at a high selectivity.
