The Invention
Researchers from UW-Madison, MIT, and NLR have developed a method for recycling Nylon 6. The method, embodied in a one-pot reactor, consists of ammonolysis followed by cyclodeamination and is realized using an environmentally benign solvent, propanol, an H3PO4 catalyst, and occurs at a low reaction temperature of 180oC. The reaction yields ε-caprolactam, the key monomer used to create pristine Nylon 6 polymer.
