Abstract
The present invention relates to compositions and processes for producing borohydride compounds. In particular, the present invention provides efficient processes and compositions for the large-scale production of borohydride compounds.
Claims28
A process for producing borohydride compounds, comprising:
- (A) reacting a borate of the formula YBO2 with CO2 and H2O to obtain YHCO3 and B2O3;
- (B) converting the YHCO3 to Y2O, CO2, and H2O;
- (C) reacting the B2O3 with C and X2 to obtain BX3 and CO2;
- (D) reacting methane with Y2O to obtain Y, carbon monoxide and H2;
- (E) reacting the Y with H2 to obtain YH;
- (F) reacting the BX3 with the YH to obtain YHBX3;
- (G) separately reacting BX3 with H2 to obtain B2H6 and HX;
- and
- (H) reacting the YHBX3 with B2H6 to obtain YBH4 and BX3,
- wherein Y is selected from the group consisting of the alkali metals, pseudo-alkali, an ammonium ion, and quaternary amines of formula NR4+, wherein R is independently selected from H and straight or branched C1 to C4 alkyl groups;
- and
- wherein X is selected from the group consisting of halides, alcohols, alkoxides, chalcogens, and chalcogenides.
