Abstract: Abstract: Disclosed is a method for producing e-caprolactam from 3-oxoadipic acid, which is suitable as a biomass resource. The method for producing e-caprolactam includes a step 1 for mixing at least one selected from the group comprising 3-oxoadipic acid and salts thereof with a catalyst and a solvent in the presence of hydrogen and generating 3-hydroxyadipic acid, and a step 2 for reacting the 3-hydroxyadipic acid, salt thereof, carboxylic acid derivative thereof, or mixture of these that is the product of step 1 with hydrogen and ammonia.

Abstract: The present invention is a method for producing e-caprolactam via adipamide that serves as an intermediate. This method for producing e-caprolactam is characterized by comprising a lactamization step wherein adipamide produced from a starting material compound is reacted with hydrogen and ammonia in the presence of a catalyst which contains a metal and/or a metal compound having hydrogenation ability and a metal oxide that mainly contains an oxide of one or more metal elements selected from the group consisting of metal elements of the fourth to sixth rows in groups 5, 7 to 14 of the periodic table. This method is capable of enhancing the selectivity of e-caprolactam.

Abstract: Disclosed is a method for selectively producing e-caprolactam from a substance, as a raw material, which can be derived from biomass resources, through a short reaction step while inhibiting production of by-products, and without producing ammonium sulfate as a by-product. The method for producing e-caprolactam includes a step for causing a specific compound, which can be derived from biomass resources, such as a-hydromuconic acid, 3-hydroxyadipic acid or 3-hydroxyadipic acid-3,6-lactone, salts of these compounds, or the like, to react with hydrogen and ammonia.

Abstract: A method for selective production of µ-caprolactam, wherein a substance inducible from a biomass resource is used as a material; the reaction process is short; ammonium sulfate is not produced as a by-product; and production of by-products is suppressed; is disclosed. The method for producing µ-caprolactam comprises the step of reacting a particular compound inducible from a biomass resource, such as ±-hydromuconic acid, 3-hydroxyadipic acid, or 3-hydroxyadipic acid-3,6-lactone, or a salt thereof with hydrogen or ammonia.
