The present invention relates to a method for producing borazane (NH3-BH3). The method includes: providing a reactor (1), provided with stirring means and a thermostat set to a temperature of θ1 to 40 °C; injecting anhydrous liquid ammonia (NH3(l)) into said reactor (1); injecting a borane-amine complex (Am.BH3) into said reactor (1) containing the anhydrous liquid ammonia (NH3(l)) while stirring, wherein said borane-amine complex (Am.BH3), the corresponding amine (Am) of which is only soluble in anhydrous liquid ammonia at a rate of less than 10 g in 100 g of ammonia at 20 °C, is injected in an amount such that the molar ratio R = anhydrous liquid ammonia (NH3(l)) / borane-amine complex (Am.BH3) is no lower than 5; stirring the mixture; halting the stirring and obtaining, within said reactor (1), two demixed phases: a light phase (1a) made up essentially of an anhydrous liquid ammonia solution (NH3(l)) containing borazane, and a heavy phase (1b) made up essentially of the amine (Am) corresponding to the injected borane-amine complex (Am.BH3); isolating said borazane and vacuum drying same; said temperature θ1 being no lower than the melting temperature of said borane-amine complex (Am.BH3). |
