Abstract: A method for selective production of ε-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 ε-caprolactam comprises the step of reacting a particular compound inducible from a biomass resource, such as α-hydromuconic acid, 3-hydroxyadipic acid, or 3-hydroxyadipic acid-3,6-lactone, or a salt thereof with hydrogen or ammonia.

Abstract: A method and a plant are disclosed for purifying lactams, particularly lactams obtained by cyclizing hydrolysis of aminonitrile. The purification of ε-caprolactam obtained by cyclizing hydrolysis of aminocapronitrile is described which includes eliminating the ammonia from the reaction medium of the hydrolysis, then recovering the lactam from the medium in purified form. The recovery is carried out by performing at least a distillation of the lactam in the presence of a base producing optionally a fronts fraction having compounds more volatile than the lactam, a fraction having the lactam to be recovered to the degree of desired purity and a distillation tails having the lactam and compounds less volatile than the lactam. The distillation tails are treated by various processes such as evaporation in thin layers to recover the major part of the caprolactam and recycling the latter in the purification process.
