摘要
The present invention relates to a method for obtaining borazane, said method being suitable for obtaining borazane containing a low level of impurities. The borazane (obtained by reaction of at least one ammonium salt with at least one alkali and/or alkaline earth metal borohydride) in solution in THF is selectively precipitated with a non-solvent. The precipitated borazane can further be purified by selective dissolution. The borazane obtained after selective precipitation and dissolution contains less than 1% by weight of impurities and/or does not exhibit exothermic decomposition in the solid state with a temperature range of the endothermic melting peak above 110° C.
