PROBLEM TO BE SOLVED: To provide a method for producing butadiene with high selectivity which uses an acetaldehyde and an alcohol as raw materials.SOLUTION: There is provided a method for producing a butadiene which uses an acetaldehyde and an alcohol represented by the general formula (I) as raw materials and uses a catalyst containing an oxide (component A) of at least one metal A selected from the group consisting of Groups IV and V of the Periodic Table and an oxide (component B) of at least one metal B selected from the group consisting of Groups I and III of the Periodic Table. The metal A preferably is zirconium, hafnium and tantalum and the metal B preferably is sodium, barium, lanthanum and yttrium. (Rand Rrepresent a hydrogen atom or an aliphatic hydrocarbon group having 1 to 20 carbon atoms and may be the same or different.) |
