  • METHOD FOR PRODUCING BORAZANE
    Publication number: 20180251380
    Abstract: A method for producing borazane, includes the synthesis of the borazane by reacting (metathesis reaction) at least one ammonium salt with at least one borohydride, the at least one borohydride being selected from the alkali metal borohydrides and the alkali-earth metal borohydrides. The (metathesis) reaction is carried out with gaseous ammonia flushing; gaseous ammonia being co-liquefied with the at least one borohydride and gradually with borazane as the borazane is synthesized.
