OF THE DISCLOSUREMETHOD FOR PRODUCING CON=VrED DIOTEFIN AND APPARATUS FOR PRODUCTICTo provide a method fer producing a conjugated diciefin that can suppress reaction byproducts with high boiling pojnt from remaining in steps following a quenching step by a quenching tower, and a method for producing a conjugated dialefin (e.g., 1,3-butadiene) that cah be used as a raw material for synthetic rubber, resin and the like, even when using an industrial grade mixed hydrocarbon that. may not necessarily have a high purity as a raw material to produco the conjugated diolefin butadiene), provlded is a method forproducing a conjugated diolefih, which includes a step of proncing a product gas by reaction containing a conjugated diolefin by feeding a hydrocarbon containing a monoolefin having 4 or more carbon atoms and oxygen to a reactor accommodated with a. catalyst which comprises a metal oxide and a carrier, and a step of seeding the product gas by reaction to a quenching tower and washing with a quenching agent, wherein an organic amine aqueous solution is used as the guencning agent. |
