Abstract: A method of producing ε-caprolactam from 3-oxoadipic acid includes: step 1 of mixing at least one selected from the group consisting of 3-oxoadipic acid and salts thereof with a catalyst and a solvent in the presence of hydrogen to produce 3-hydroxyadipic acid; and step 2 of reacting the 3-hydroxyadipic acid which is a product of step 1, a salt or carboxylic acid derivative thereof, or a mixture of these with hydrogen and ammonia.
