Method for producing 1,3-butadiene |
| abstract |
An object of the present invention is to provide a method for producing butadiene which can suppress the precipitation of by-products and block the cooling tower and piping, and can stably operate continuously. The present invention provides a step of obtaining a product gas containing 1,3-butadiene by an oxidative dehydrogenation reaction of a source gas containing n-butene and a molecular oxygen-containing gas in the presence of a metal oxide catalyst, and the product gas It is a manufacturing method of 1, 3- butadiene which has the process to cool and makes the cooling solvent containing an organic solvent and alkali metal compound aqueous solution contact gas in the above-mentioned cooling process. |
