  • Patent number: 11753372
    Abstract: A new process for the production of epsilon caprolactam (CPL) from 6-aminocaproic acid (6-ACA) can be obtained either from traditional petro chemical processes or can be obtained from biochemical processes. With the proposed process, the reaction time for conversion of 6-aminocaproic acid to the Nylon 6 monomer is shorter and significant energy savings are possible which is advantageous for industrial scale production. The conversion of 6-aminocaproic acid to the Nylon 6 monomer runs at atmospheric pressure and in the final product epsilon caprolactam with no oligomers formation of significance is obtained.

  • Patent number: 11746082
    Abstract: A system and method for efficiently and sustainably producing propylene and acrylonitrile is disclosed which utilizes biodegradable materials, combustible materials that produce carbon dioxide and/or carbon monoxide. According to one embodiment of the invention, a source of carbon dioxide and/or carbon monoxide is utilized and the carbon dioxide and/or carbon monoxide is electrochemically reduced to ethylene. Dimerization is applied to separate the ethylene to produce 1-butene; which is isomerized to produce 2-butene. The 2-butene is metathesized to produce propylene. The propylene may then be subject to ammoxidation as desired in order to produce acrylonitrile.
