Application: Sodium hypophosphite monohydrate can be used as Synthesis of NINP nanoparticles from nickel acetate tetrahydrate under microwave irradiation. Aliphatic and aromatic ketones were oxidized to hydrogen donors of corresponding alcohols by enantioselective transfer in the presence of nail catalyst. N, N-methyl-methyl-coolamine (DMF) was used as a solvent to catalyze the cooling reaction of waste grains to improve the adsorption capacity of heavy metal ions.。
