Application

Sodium hypophosphite monohydrate can be used as a:
  • Reducing agent in the synthesis of nickel nanoparticles (NiNP) from nickel acetate tetrahydrate under microwave irradiation.
  • Hydrogen donor in the enantioselective transfer hydrogenation of aliphatic and aromatic ketones to corresponding alcohols in presence of ruthenium catalyst.
  • Catalyst in esterification of spent grain to improve heavy metal ions adsorption capacity using N,N-dimethylformamide (DMF) as a solvent.
