METHOD OF PERFECTING PROCESS OF PRODUCING ETHYLENE OXIDE Russian patent published in 2008 - IPC C07D301/10 C07D303/04 

FIELD: chemistry.

SUBSTANCE: invention pertains to ethylene oxide and to the method of obtaining 1,2-ethanediol or a simple ether of 1,2-ethanediol, from ethylene oxide, obtained using the proposed method. The process of producing ethylene oxide involves an epoxidation reactor system, containing a volume of a high octane epoxidation catalyst. The method involves replacing part of the volume of the high octane epoxidation catalyst with a volume of highly selective catalyst and modification of the process system so as to provide for initial raw materials of the reactor of the epoxidation system, with low concentration of carbon dioxide.

EFFECT: considerable improvement in the effectiveness of the system of producing ethylene oxide due to perfection of the process and operation of the existing production system.
