Abstract
This invention relates to gas-phase synthesis of butadiene from ethanol or ethanol and acetaldehyde mixture. The method of synthesis includes ethanol or ethanol and acetaldehyde mixture conversion in the presence of a catalyst, which differs from the known methods by the carrying out of the interaction in the presence of the solid catalyst, which contains metal, chosen from the group of silver, gold or copper, and metal oxide, chosen from the group of magnesium, titanium, zirconium, tantalum or niobium oxides. The method announced is used for condensation process under the conditions of continuous flow fixed bed reactor. The invention allows to reach high yield and selectivity to butadiene and high level of conversion of the feed.
