Latest Patents

Henrik Skifs holds two recent patents that showcase his innovative methods. The first patent is titled "Synthesis of ammonium dinitramide, ADN." This invention concerns a method for producing ADN from GUDN in a single process step. In this method, GUDN is reacted with an ammonium source, such as ammonium-sulfamate, ammonium-sulfate, or ammonia, and an ion exchange results in the formation of ADN. The advantages of this process include the production of pure ADN without potassium contaminants and the requirement of a smaller amount of solvent.

The second patent is for a "Method of producing salts of dinitramidic acid." This method involves the nitration of an initial compound with a nitrating acid mixture to create dinitramidic acid in a reaction mixture. A positive ion is added to form an ion pair complex with the dinitramide ion, which precipitates in the acidic reaction mixture. The precipitate can then be separated from the mixture, and the remaining spent acid can be reprocessed for recovery. The preferred positive ion in this process is the guanylurea ion, which leads to the formation of guanylurea dinitramide.
