Recycling process of sodium metaborate to sodium borohydride

International Journal of Hydrogen Energy, 2003
Abstract Sodium borohydride ( NaBH 4 ) was synthesized by reacting sodium metaborate ( NaBO 2 ) with magnesium hydride ( MgH 2 ) or magnesium silicide ( Mg 2 Si ) by annealing (350– 750° C ) under high H 2 pressure (0.1– 7 MPa ) for 2– 4 h .

Reduction of Solid Benzophenones with Sodium Borohydride

Journal of Thermal Analysis and Calorimetry, 1998
The solvent-free reduction of benzophenone and five substituted benzophenones with sodium borohydride to the corresponding alcohols was studied by thermal analysis, X-ray powder diffractometry, NMR spectroscopy, and scanning electron microscopy. In most cases, the reaction occurs via liquid eutectic phases that are formed between the benzophenone and ...

Analytical monitoring of sodium borohydride

Analytical Methods, 2013
Sodium borohydride (NaBH4) determination, both qualitative and quantitative, is of great significance in a plethora of areas. These include NaBH4 for energy systems such as direct borohydride fuel cells and in hydrogen production and storage, as well as use as a reducing agent in organic and inorganic synthesis reactions or in electrodeposition ...

Chemoselective reductions with sodium borohydride

Canadian Journal of Chemistry, 1989
Under the appropriate reaction conditions, sodium borohydride is a highly chemoselective reducing agent. The order of reactivity among carbonyl groups is conjugated enones < ketones < conjugated aldehydes < aldehydes. In general, a carbonyl group of one type can be selectively reduced in the presence of a carbonyl group of a less reactive ...
