Patent ID: 8808662

Claim:
A process for production of a borohydride compound M(BH 4 ) y ; said process comprising steps of: (a) combining a compound of formula (R 1 O) y M with aluminum, hydrogen and titanium, wherein the titanium is present as an alloy in the aluminum or as free titanium metal, to produce a compound of formula M(AlH 3 OR 1 ) y , wherein R 1 is phenyl or phenyl substituted by at least one alkyl or alkoxy group and M is an alkali metal, Be or Mg; wherein the titanium is present at a level of at least 200 ppm based on weight of aluminum; (b) combining the compound of formula M(AlH 3 OR 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; and (c) separating M(BH 4 ) y from the byproduct mixture.
