Abstract
A method for producing butadiene, the method including: a first synthesis step of bringing a mixed gas containing hydrogen and carbon monoxide into contact with a first catalyst to obtain a primary product containing ethanol as an intermediate; and a second synthesis step of bringing the primary product into contact with a second catalyst to obtain butadiene.
