PROBLEM TO BE SOLVED: To provide a process of producing 1,3-butadiene that can efficiently produce 1,3-butadiene, which is industrially useful as a raw material of synthetic rubber, using propylene as a raw material.SOLUTION: A process of producing 1,3-butadiene includes at least the steps of: (A) disproportionating a gas containing at least gaseous propylene in the presence of a disproportionation reaction catalyst to convert the gas into a product gas containing n-butene and ethylene; (B) subjecting the reaction product gas obtained in the step (A) to a separation operation to separate and recover a fraction containing n-butene as a main component; and (C) dehydrogenating the fraction obtained in the step (B) in the presence of a dehydrogenation catalyst to produce a reaction product gas containing 1,3-butadiene. |
