A process for production of a borohydride compound M(BH 4 ) y . The process has three steps. The first step combines a compound of formula (R 1 O) y M 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(A1H 3 0R 1 )y, wherein R 1 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(A1H 3 0R 1 )y with a borate, boroxine or borazine compound to produce M(BH 4 )y and a byproduct mixture containing alkali metal and aluminum aryloxides. The third step separates M(BH 4 )y from the byproduct mixture. |
