The present invention relates to a method for producing butadiene, and according to the present invention, by using butane as a diluent gas, even if a coolant lower than the cryogenic refrigerant, it is possible to easily separate the C4 mixture and gas products except butadiene. In addition, there is an effect of providing a butadiene manufacturing method and a manufacturing apparatus that can secure high purity butadiene in the process economics and safety, such as reducing the raw material cost, improving productivity by minimizing the loss of active ingredients. |
