摘要： PROBLEM TO BE SOLVED: To provide a method capable of recovering ε-caprolactam efficiently while preventing the oligomerization and thermal decomposition of the ε- caprolactam, and recovering the ε-caprolactam from a residue discharged from a polymerization vessel containing the oligomers of the ε-caprolactam, and to provide a facility for the recovery. SOLUTION: This method for recovering ε-caprolactam comprises recovering the ε-caprolactam from an ε-caprolactam oligomer-containing residue discharged from a polymerization vessel in a process for polymerizing monomers containing at least the ε-caprolactam to produce a polyamide. Therein, the residue is brought into contact with a high temperature high pressure water at temperature of 280-450 deg.C water a pressure of 100-500 kg/cm2 to depolymerize the ε- carpolactam oligomer to recover the ε-caprolactam. The facility is provided with a reactor 1 and with a post-treatment means 2 for post-treating the product discharged from the reaction vessel 1 to recover the ε-caprolactam.

摘要： PROBLEM TO BE SOLVED: To obtain a recovered caprolactam with impurity content of a specified level or lower, by purifying an ε-caprolactam, obtained by, e.g. depolymerization of Nylon 6, using an adequate process, e.g. enrichment, recrystallization, or distillation under specified pressure and temperature conditions, to remove impurities present in the raw ε-caprolactam. SOLUTION: This ε-caprolactam(CL) is recovered from a resin composition, containing Nylon 6 normally at 10 wt.% or more, preferably 30 wt.% or more, depolymerized under heating in the presence of a catalyst. The recovered CL normally contains impurities, e.g. water and adipimide shown by the formula, normally at 5 wt.ppm or higher for the latter, when enriched to 90% or higher. It is further purified by, e.g. distillation or recrystallization, to reduce the adipimide content to 3 wt.ppm or lower. It is recommended that the distillation is effected at a reduced pressure of 20 Torr. or lower and 150 deg.C or lower, and the recrystallization is effected in the presence of an organic or aqueous solvent.

摘要： PURPOSE: To purify recovered ε-caprolactam into a highly pure product useful as a raw material for fiber in an industrially advantageous manner by purifying the recovered ε-caprolactam obtained by depolymerizing a thermoplastic resin containing nylon 6 as a main component. CONSTITUTION: The method for purifying recovered ε-caprolactam comprises depolymerizing a thermoplastic resin containing nylon 6 as a main component [e.g. fibrous structures, fiber wastes. resin structures or resin wastes comprising nylon 6 in an amount of >=50wt.%, cellulosic fibers or polyurethane in an amount of 0.1-30wt.%, or protein fibers, a polyacrylate, polyethylene terephthalate or nylon 66]. and subsequently purifying the recovered ε-caprolactam. The depolymerization is preferably performed by depolymerizing the component A in the presence of a phosphoric acid (salt) catalyst and water, and the purification is performed by adding 0.01-20wt.% of an alkali hydroxide to the recovered ε-caprolactam.
