Sodium borohydride Chemical Properties,Usage,Production |
Chemical Properties
White solid |
|
Usage
Nanocrystalline superlattices in gold colloid solution have been prepared by ligand-induction using AuCl3 reduced with sodium borohydride.1 Nucleophilic addition of hydride ion from sodium borohydride is an inexpensive alternative method for the Baylis-Hillman reaction to form [E]-α-methylcinnamic acids.2 |
|
Usage
Sodium Borohydride is used as a reagent in the reduction of amino acids and their derivatives. Also used in the catalysis of ammonia borane dehydrogenation. |

General Description
Sodium borohydride is a white to grayish crystalline powder. Sodium borohydride is decomposed by water to form sodium hydroxide, a corrosive material, and hydrogen, a flammable gas. The heat of this reaction may be sufficient to ignite the hydrogen. The material itself is easily ignited and burns vigorously once ignited. Sodium borohydride is used to make other chemicals, treat waste water, and for many other uses. |

Air & Water Reactions
Hydrolysis generates enough heat to ignite adjacent combustible material [Haz. Chem. Data 1966]. Dissolves in water with liberation of heat, may steam and spatter. Solution is basic (alkaline). Reaction of water with the borohydride liberates flammable hydrogen gas. Sodium borohydride burns in air [Lab. Gov. Chemist 1965]. |
|
Reactivity Profile
Sodium borohydride is a powerful reducing agent. A chemical base. Absorbs moisture readily forming caustic solution. which attacks aluminum and zinc. A violent polymerization of acetaldehyde results from the reactions of acetaldehyde with alkaline materials such as sodium hydroxide. Calcium oxide or sodium hydroxide react with phosphorus pentaoxide extremely violently when initiated by local heating [Mellor 8 Supp.3:406 (1971]. Using potassium hydroxide to dry impure tetrahydrofuran, which contains peroxides, may be hazardous. Explosions have occurred in the past. Sodium hydroxide behaves in a similar way as potassium hydroxide [NSC Newsletter, Chem. Soc. 1967]. Ignition occurs if a mixture of the hydride and sulfuric acid is not cooled. Contact of glycerol and Sodium borohydride leads to ignition, other glycols and methanol are exothermic but do not ignite. |

Health Hazard
Solid irritates skin. If ingested can form large volume of gas and lead to a gas embolism. |
|
Fire Hazard
Behavior in Fire: Decomposes and produces highly flammable hydrogen gas. |
