FIELD: chemistry.
SUBSTANCE: present invention relates to methods of producing a catalytic composition, to the method of producing olefin oxide and method of producing 1,2-diol or 1.2-diol ether. Described is a method of producing a catalytic composition, involving deposition of silver on a carrier and deposition of a promoter - alkali metal on the carrier. The alkali metal contains potassium in amount of at least 10 mcmol/g and lithium in amount of at least 1 mcmol/g in terms of mass of catalytic composition. The alkali metal is deposited on the carrier before depositing silver, at the same time or after depositing silver on the carrier. Described is a method of producing a catalytic composition, involving use of potassium as a promoter in amount of at least 10 mcmol/g and sodium in amount of at least 5 mcmol/g in terms of mass of the catalytic composition. Description is given of a method of producing olefin oxide by reacting olefin, which has at least three carbon atoms, with oxygen in the presence of a catalytic composition, obtained using the method described above. This invention also pertains to the method of producing 1,2-diol or 1,2-diol ether using olefin oxide, obtained using the said method.
EFFECT: increased selectivity and stability of the catalytic composition.
