  • Chlorinolysis process for producing carbon tetrachloride
    Patent number: 11787756
    Abstract: A process for producing carbon tetrachloride comprising reacting i) chlorine, ii) a C1 chlorinated compound comprising 1 to 3 chlorine atoms, and iii) a carbon/second chlorine source, wherein the second chlorine source comprises a range of multichlorinated C3 hydrocarbons, said range being obtained as waste products from the industrial production of 1,1,1,2,3-pentachloropropane and/or 1,1,3,3-tetrachloropropene.
    Type: Grant
    Filed: January 13, 2021
    Date of Patent: October 17, 2023
    Assignee: SPOLEK PRO CHEMICKOU A HUTNI VYROBU A.S.
    Inventors: Pavel Kubicek, Vlastimil Briza, Tomas Pittner, Tomas Riedel

  • Chlorinolysis process for producing carbon tetrachloride
    Patent number: 10919823
    Abstract: A chlorinolysis process for producing carbon tetrachloride comprising providing a chlorination zone at an operating temperature of from 400 to 600° C. with i) chlorine, ii) a C1 chlorinated compound comprising 1 to 3 chlorine atoms and iii) a carbon/second chlorine source to produce a reaction mixture, and, after a residence time, extracting a product mixture from the chlorination zone, the product mixture comprising carbon tetrachloride and optionally perchloroethylene, wherein the product mixture comprises a higher molar content of carbon tetrachloride than perchloroethylene, if present.
