Abstract: A process for obtaining borazane (NH3—BH3) includes introducing anhydrous liquid ammonia (NH3(l)) into a reactor thermostatically regulated to between a temperature ?1 and 40° C.; introducing, with stirring, into the reactor an amine borane complex (Am.BH3), the corresponding amine (Am) of which is soluble in anhydrous liquid ammonia only to a proportion of less than 10 g in 100 g of ammonia at 20° C., being introduced in an amount such that the mole ratio R=(NH3(l))/(Am.BH3) is greater than or equal to 5; stirring the mixture; stopping the stirring to obtain two demixed phases: a light phase constituted essentially of a solution of anhydrous liquid ammonia (NH3(l)) containing borazane; and a heavy phase constituted essentially of the amine corresponding to the amine borane complex introduced; isolating the borazane and drying under vacuum thereof; the temperature ?1 being greater than or equal to the melting point of the amine borane complex.
