Abstract: In the method of the present invention, 1,3-butadiene is produced by vaporizing an ethanol feedstock in a vaporizer (104), feeding the resulting into two or more parallel first reactors (108) to convert the ethanol to acetaldehyde in the presence of a first catalyst, supplying the resulting intermediate gas to a second reactor (110) to convert the ethanol and acetaldehyde to 1,3-butadiene in the presence of a second catalyst, purifying the resulting crude gas containing 1,3-butadiene by a gas-liquid separator (112), a first distillation column (114), a fourth reactor (116), a second distillation column (118), and mixing one of both of a part of the ethanol-containing gas and an acetaldehyde-containing gas obtained in the second distillation column (118) are mixed with the intermediate gas, thereby adjusting an ethanol/acetaldehyde molar ratio in the intermediate gas to 1 to 100.
