Process for production of a borohydride compound
A process for production of a borohydride compound. The process comprises combining a compound comprising boron and oxygen with an adduct of alane.
1. A process for production of a borohydride compound; said process comprising combining a compound comprising boron and oxygen with an adduct of alane and a C 3 -C 12 tertiary amine.
2. The process of claim 1 in which the compound comprising boron and oxygen is a compound having at least one oxygen atom per boron atom.
3. The process of claim 2 in which the borohydride compound is sodium borohydride.
4. The process of claim 1 in which the compound comprising boron and oxygen is an acid or salt comprising BO 2 − or B 4 O 7 −2 .
5. The process of claim 4 in which the acid or salt comprising BO 2 − or B 4 O 7 −2 is NaBO 2 or Na 2 B 4 O 7 .
6. The process of claim 5 in which the borohydride compound is sodium borohydride and the acid or salt comprising BO 2 − or B 4 O 7 −2 is NaBO 2 .
7. A process for production of a borohydride compound; said process comprising combining an acid or salt comprising BO 2 − or B 4 O 7 −2 with aluminum, hydrogen and a C 3 -C 12 tertiary amine.
8. The process of claim 7 further comprising a catalyst selected from the group consisting of powders of the transition metals and their oxides; oxides of aluminum and silicon; and alloys of formula AB 2 , AB 5 , AB or A 2 B, wherein A and B are transition metals; and combinations thereof.
9. The process of claim 8 in which the borohydride compound is sodium borohydride.
10. The process of claim 7 in which the acid or salt comprising BO 2 − or B 4 O 7 −2 is NaBO 2 or Na 2 B 4 O 7 .
11. The process of claim 10 in which the borohydride compound is sodium borohydride and the acid or salt comprising BO 2 − or B 4 O 7 −2 is NaBO 2 .
