METHOD FOR OLEFINES EPOXIDATION AND APPLIED CATALYST Russian patent published in 2008 - IPC C07D301/10 B01J23/64 C07C29/10 C07C41/03 C07C213/04 B01J37/03 

FIELD: chemistry.

SUBSTANCE: method for olefine epoxidation is invented which includes the reaction of the raw material containing olefine, oxygen and organic halogenide, in presence of the catalyst containing silver and rhenium precipitated on the carrier where the catalyst contains rhenium at 1.5 mol/kg of the catalyst mass, at maximum, and 0.0015 mmol/m³ of the carrier surface, at maximum, and where the reaction temperature is increased so as to partially reduce the effect of catalyst loss, and the halogenide is presented in relative Q amount which is maintained constant and where the relative amount of Q is the ratio of the effective molar amount of the active halogen compound in the raw material, to the effective molar amount of hydrocarbon, in the raw material. The invention also implies the method for producing the 1,2-diol, the simple ether of the 1,2-diol and/or alkanolamine and the catalyst to be applied in the said method.

EFFECT: stability of catalyst activity is increased.
