| description | The invention relates to a gas-phase synthesis of butadiene from ethanol or from a mixture of ethanol and acetaldehyde. The method of production includes conversion of ethanol or a mixture of ethanol with acetaldehyde in the presence of a catalyst, wherein the reaction is carried out in the presence of a solid catalyst with a mesoporous Zr-containing zeolite having a BEA type structure and at least one metal in a zero oxidation state selected from the group: silver, copper and gold. The claimed method is suitable for carrying out the reaction under continuous flow conditions in the reactor with a fixed bed of catalyst. The invention makes possible to achieve a high yield of butadiene with high selectivity to butadiene and high stability of the catalyst. |
