METHOD AND SYSTEMS FOR EPOXIDATION OF OLEFIN

FIELD: organic chemistry, chemical technology. ^ SUBSTANCE: invention relates to a method for the epoxidation reaction of olefin. Method involves interaction of the parent olefin-containing raw, oxygen and an agent modifying reaction in the presence of a silver-base catalyst. Agent modifying the reaction presents in the relative amount Q that represents the ratio of effective molar amount of active parts of reaction modifying agent presenting in the parent raw to the effective molar amount of hydrocarbons presenting in the parent raw. Proposed method involves the following steps: interaction in the first stage of process wherein Q values are equal to Q1 and the following interaction in the second step of process wherein the composition of the parent raw differs from composition of the parent raw used in the first step of process and Q value is equal to Q2 wherein value Q2/Q1 = 0.5-1.5. Also, invention relates to a method for synthesis of 1,2-diol or 1,2-diol ether, system for realization of method, the end product and a computer system suitable for using with proposed method. ^ EFFECT: improved method of synthesis. ^ 20 cl, 2 ex
