SINGLE-STEP METHOD OF PRODUCING BUTADIENE Russian patent published in 2012 - IPC C07C11/167 C07C1/20 B01J23/54 B01J23/58 B01J23/648 B01J23/76 B01J23/78 B01J23/847

Abstract RU 2440962 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a single-step method for gas-phase production of butadiene, involving conversion of ethanol or a mixture ethanol and acetaldehyde in the presence of a catalyst, characterised by that the reaction takes place in the presence of a solid-phase catalyst containing a metal selected from: silver, gold or copper, and a metal oxide selected from magnesium, titanium, zirconium, tantalum or niobium oxide.

EFFECT: method provides high output of butadiene, selectivity of the process and high degree of conversion of material.
