METHOD AND SYSTEM FOR OLEFIN EPOXYDATION Russian patent published in 2007 - IPC C07D301/10 C07C303/04 C07C31/20 C07C41/03 C07B61/00 

FIELD: organic chemistry.

SUBSTANCE: claimed method includes interaction of raw materials containing olefin, oxygen and reaction modifying agent in presence high selective silver-based catalyst at reaction temperature of T. Relative amount of reaction modifying agent is Q, wherein Q is ratio of effective molar amount of active sites of reaction modifying agent representing in raw materials to effective molar amount of hydrocarbon representing in raw materials. Epoxydation process is carried out in the first process phase wherein T=T₁ and Q=Q₁. Further process is carried out in the second process phase at T=T₂ and Q=Q₂, wherein T₂ and Q₂ are differ from T₁ and Q₁. Q₂ is calculated according to equation Q₂ = Q₁ + B(T₂ - T₁) wherein B represents constant more than 0. Also disclosed are method for production of 1,2-diol or 1,2-diol ether; reaction system used in investigation; computer program product for calculations and computer system including said program product and information processing system.

EFFECT: improved method and system for olefin epoxydation.
