Abstract
The invention concerns a method for making ADN from GUDN in one single process step. GUDN is reacted with an ammonium source (ammonium-sulfamate, ammonium-sulfate, ammonia) and an ion-change gives ADN from GUDN in one process stage. The advantages are that the process gives pure ADN without potassium contaminants and that a smaller amount of solvent is necessary.
