Abstract
A method of purifying caprolactam by treating the impurities with hydrogen in the presence of a hydrogenation catalyst, characterized by the operations comprising passing the hydrogen through an aqueous solution of the caprolactam at a temperature below the boiling point thereof, and recover the caprolactam from the reaction liquid.
