Sodium Borohydride - Applications
Sodium Borohydride is commonly used in the production of Sodium Dithionite
(Sodium Hydrosulphite) from Sulphur Dioxide. Sodium dithionite as well as
a good reducing agent for the reduction of aromatic nitro and diazonium
compounds to anilines it is also used as a bleaching agent in both the
wood pulp and dyeing industries.
Sodium Borohydride reduces aldehydes and ketones to give the related alcohols. These reducing properties are used in the
pharmaceuatical industry for the production of various antibiotics including Chloramphenicol, Dihydrostreptomycin, and
Thiophenicol. It is also used in various stagea for the production of steroids and vitamin A.
Sodium borohydride is used as reducing agent in the synthesis of gold nanoparticles. This process can be seen below:
500 mL Milli-Q H2O + 1 mL of 10-1 M HAuCl4 + 0.05 g NaBH4 ==> 0.2 mM AuNPs
Sodium Borohydride has been used in earlier stages of development as a solid state hydrogen storage source.
