摘要:
The invention relates to a method for the continuous production of caprolactam from waste containing polyamide, comprising a) depolymerisation of the waste containing polyamide, whereby a caprolactam raw material and, where applicable, a flow containing secondary constituents or additives is obtained, and b) irradiation of the caprolactam raw material with UV radiation.
