| titleOfInvention | Method for producing butadiene |
| abstract | 【Task】 To produce butadiene stably over a long period of time without changing the raw materials, catalyst and reaction conditions in the reaction process. [Solution] a reaction step of reacting n-butene and molecular oxygen to produce a first gas containing butadiene, an absorption step of absorbing a part or all of the first gas containing butadiene in a solvent in an absorption tower, and And a stripping step of stripping a second gas containing butadiene from the solvent in which the first gas has been absorbed in a stripping tower, and the concentration of the polymerizable aldehyde in the solvent in the concentration section of the stripping tower is 1 The butadiene production method maintained at 0.0% by weight or less can produce butadiene stably over a long period of time without changing the raw materials, catalyst and reaction conditions in the reaction step. [Selection figure] None |
