  • Patent number: 5932724
    Abstract: The present invention provides an efficient process for the recovery of caprolactam from polycaprolactam-containing waste material. The present process for depolymerizing multi-component waste material comprising polycaprolactam and non-polycaprolactam components to form caprolactam comprises the step of: in the absence of added catalyst, contacting the multi-component waste material with superheated steam at a temperature of about 250.degree. C. to about 400.degree. C. and at a pressure within the range of about 1 atm to about 100 atm and substantially less than the saturated vapor pressure of water at the temperature wherein a caprolactam-containing vapor stream is formed. The formed caprolactam may then be used in the production of engineered resins and fibers.
