FIELD: chemistry.
SUBSTANCE: catalyst contains silver, applied on profiled carrier with geometric configuration in form of hollow cylinder, in which ratio of length to outer diameter lies within interval from 0.3 to 2, and inner diameter constitutes up to 30% of outer diameter of said profiled carrier with assumption that when carrier contains more than one channel, inner diameter is considered to be the diameter of one channel with area of transverse section equal to the sum of areas of transverse sections of all channels. Described is method which includes obtaining profiled carrier with geometric configuration in form of hollow cylinder described above, and application of silver on profiled carrier. Described is method of obtaining ethylene oxide which includes: contacting under suitable epoxidation conditions of raw material flow, containing ethylene and oxygen, with described above catalyst. Also described is method of obtaining ethylene glycol, ethylene glycol ester, or 1,2-alkanolamine, which includes using ethylene oxide obtained by described above method and its conversion to ethylene glycol, ethylene glycol ester or 1,2-alaknolamine.
EFFECT: increase of initial activity and stable activity.
