    • The present invention relates to processes for producing borohydride compounds. In particular, the present invention provides efficient processes and compositions for the large-scale production of borohydride compounds of the formula YBH4 by the reaction of a boron-containing compound represented by the formula BX3 with hydrogen or an aldehyde to obtain diborane and HX, and reacting the diborane with a Y-containing base selected from those represented by the formula Y2O, YOH and Y2CO3 to obtain YBH4 and YBO2. Y is selected from the group consisting of the alkali metals, pseudo-alkali metals, alkaline earth metals, an ammonium ion, and quaternary amines of the formula NR4+, wherein each R is independently selected from hydrogen and a straight- or branched-chain C1-4 alkyl group, and X is selected from the group consisting of halide ions, —OH, —R′ and —OR′ groups, chalcogens, and chalcogenides, wherein R′ is a straight- or branched-chain C1-4 alkyl group.
    • 本发明涉及生产硼氢化合物的方法。 特别地,本发明提供了通过式BX3表示的含硼化合物与氢或醛反应而大规模生产式YBH4的硼氢化合物的有效方法和组合物,以获得乙硼烷和HX,以及 使乙硼烷与选自由式Y 2 O,YOH和Y 2 CO 3表示的Y含量碱反应,得到YBH 4和YBO 2。 Y选自碱金属,假碱金属,碱土金属,铵离子和式NR4 +的季胺,其中每个R独立地选自氢和直链或支链的 - 链C 1-4烷基,X选自卤离子,-OH,-R'和-OR'基,硫属元素和硫族化物,其中R'是直链或支链C1- 4烷基。
