FIELD: chemistry. ^ SUBSTANCE: principle refers to the method of producing olefin oxide, method of application of the produced olefin oxide and the production of 1,2-diol or simple ether 1-,2-diol and catalytic composition. The mentioned catalytic composition for the production of olefin oxide contains silver and activating agent, that consists of an alkaline metal on a bearer where the activating alkaline metal contains potassium whose quantity is not less than 5 mcmol/g of metal relative to the mass of the catalytic composition and not less than 1 mcmol/g alkaline metal from the group that contains lithium, sodium and there mixtures in which the mentioned bearer contains calcium carbonate joined with silver. The relative mass of silver: calcium carbonate is 1:5 to 1:100, and the unit surface area of the bearer is from 1 m/g to 20 m/g, and the apparent porosity of the bearer is 0.05 ml/g to 2 ml/g. The explained method of producing olefin oxide, include interaction of olefin, that has 3 or more carbon atoms, with oxygen in the presence of the above mentioned catalytic system, and the method of producing 1,2-diol or simple ether 1,2-diol, in which the olefin oxide is produced from the explained method. ^ EFFECT: increasing of selectivity, activity and stability of catalyst. ^ 10 cl, 5 tbl, 37 ex |
