  • METHOD FOR PRODUCING TRIFLUOROAMINE OXIDE
    Publication number: 20230331552
    Abstract: There is provided a method for producing trifluoroamine oxide. The method includes a step of preparing an intermediate product by simultaneously providing and reacting nitrogen trifluoride and nitrous oxide under the presence of a SbF5 reaction catalyst; and a step of producing trifluoroamine oxide by reacting the intermediate product with potassium fluoride. The step of reacting the intermediate product with potassium fluoride is performed under atmospheric pressure and room temperature.

  • METHOD AND APPARATUS FOR EFFECTIVE PREPARATION OF TRIFLUOROAMINE OXIDE
    Publication number: 20210047184
    Abstract: The present invention relates to a preparation method of trifluoroamine oxide which comprises the steps of producing an intermediate product by reacting nitrogen trifluoride and nitrous oxide in the presence of a reaction catalyst wherein the unreacted gas containing nitrogen (N2) produced in the course of the reaction is removed and instead nitrogen trifluoride and nitrous oxide are injected additionally; and producing trifluoroamine oxide by reacting the intermediate product with sodium fluoride.
