[Problem] The purpose of the present invention is to provide a method for producing a conjugate diolefin of high purity. [Solution] This method for producing a conjugate diolefin comprises a step for compressing a gas containing a conjugate diolefin, which is generated when a starting gas containing a C4 or higher monolefin and an oxygen containing gas are fed to a reactor where the same are brought into contact with a catalyst and undergo oxidative dehydrogenation, forming a liquefied gas therefrom, and rinsing the liquefied gas using water. |
