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: 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: A method for producing butadiene from 2,3-butanediol with high selectivity without using a radioactive substance is disclosed. The method for producing butadiene comprises the step of dehydrating 2,3-butanediol in the presence of a catalyst containing an alkali metal salt of phosphoric acid such as an alkali metal dihydrogen phosphate supported on silica. Preferred examples of the alkali metal herein include K, Rb, and Cs. The catalyst is preferably a catalyst prepared by calcination of the silica to which the alkali metal of phosphoric acid is attached.
