PROCESS FOR OBTAINING BORAZANE, SUITABLE FOR OBTAINING BORAZANE DE GRANDE, OR VERY HIGH PURITY; BORAZANE OF VERY LARGE PURITY

摘要

The present invention relates to a process for obtaining borazane, said process suitable for obtaining borazane containing a low level of impurities. Borazane (obtained by reaction of at least one ammonium salt with at least one alkali metal and / or alkaline earth metal borohydride) dissolved in THF is selectively precipitated with a nonsolvent. Said borazane precipitate can be further purified by selective dissolution. The subject of the present invention is also a borazane containing less than 1% by weight of impurities and / or not exhibiting an exothermic decomposition in the solid state with a temperature range of the endothermic melting peak above 110 ° C.
