METHOD FOR EPOXIDATION OF OLEFINS Russian patent published in 2007 - IPC C07D301/12 

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention relates to a method for the catalytic epoxidation reaction of (C₂-C₆)-olefins with hydrogen peroxide in the flow-type continuous reaction system. The reaction mixture is passed through an immobile catalytic layer with the re-flowing regimen process with at least partial removal of reaction heat formed during the reaction. The process can be carried out in the multiple reaction mixture comprising an aqueous liquid phase enriched with hydrogen peroxide containing methanol and a liquid organic phase enriched with propane. Methanol can be used as an organic solvent. Invention provides improves the conversion degree and selectivity with respect to the end product.

EFFECT: improved method of synthesis.
