METHOD FOR EPOXIDATION OF OLEFINS Russian patent published in 2006 - IPC C07D301/12 

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention relates to a method for catalytic epoxidation of (C₂-C₆)-olefins with hydrogen peroxide. Method is carried out in the flow-type reaction system of continuous effect wherein the reaction mixture is passed through a immobile catalytic layer inside of reactor fitted with a cooling device and in simultaneous maintaining the temperature profile into the reactor wherein the cooling medium temperature in the cooling agent is at least 40°C and the maximal temperature inside of the catalytic layer is 60°C, not above. Invention provides improving the conversion degree and selectivity of the product by using the conventional systems.

EFFECT: improved method of synthesis.
