    • A process for production of a borohydride compound M(BH4)y. The process has three steps. The first step combines a compound of formula (R1O)yM with aluminum, hydrogen and a metallic catalyst containing at least one metal selected from the group consisting of titanium, zirconium, hafnium, niobium, vanadium, tantalum and iron to produce a compound of formula M(AlH3OR1)y, wherein R1 is phenyl or phenyl substituted by at least one alkyl or alkoxy group; M is an alkali metal, Be or Mg; and y is one or two; wherein the catalyst is present at a level of at least 200 ppm based on weight of aluminum. The second step combines the compound of formula M(AlH3OR1)y with a borate, boroxine or borazine compound to produce M(BH4)y and a byproduct mixture containing alkali metal and aluminum aryloxides. The third step separates M(BH4)y from the byproduct mixture.
    • 制备硼氢化合物M(BH4)y的方法。 该过程有三个步骤。 第一步是将式(R1O)yM的化合物与铝,氢和含有选自钛,锆,铪,铌,钒,钽和铁中的至少一种金属的金属催化剂组合以制备式 M(AlH 3 OR 1)y,其中R 1是苯基或被至少一个烷基或烷氧基取代的苯基; M是碱金属,Be或Mg; y是一两个; 其中所述催化剂以基于铝的重量的至少200ppm的含量存在。 第二步将式M化合物(AlH 3 OR 1)y与硼酸盐,环硼氧烷或环硼氮烷化合物结合,生成M(BH4)y和含有碱金属和铝酰氧化物的副产物混合物。 第三步骤将M(BH4)y与副产物混合物分离。
