SODIUM HYPOPHOSPHITE

FORMULA : NaH2PO2.H2O
ORIGIN : China
PACKING : 25kg/bag
APPLICATION : Nickel Plating chemistry, construction chemicals ...

Short description

Chemical name: Sodium hypophosphite, NaH2PO2 Other names: SODIUM HYPOPHOSPHITE, Phosphinic acid, sodium salt; sodium monophosphate; Hypophosphorous Acid Monosodium Salt; Sodium hypophosphite; Phosphinic Acid Monosodium Salt; Sodium Phosphinate; Fosfinato de sodio; Phosphinate de sodium. Chemical formula: NaH2PO2.H2O Purity: 100% CAS number: 7681-53-0, 10039-56-2 (monohydrate) Appearance: White crystal Applications: Sodium hypophosphite is mainly used for electroless nickel plating (Ni-P). With this method, a durable nickel-phosphorus film can coat objects with irregular surfaces, such as in avionics, aviation and the petroleum field. Sodium hypophosphite is capable of reducing nickel ions in solution to metallic nickel on metal substrates as well as on plastic substrates. The latter requires that the substrate is activated with fine particles of palladium. The resulting nickel deposit contains up to 15% phosphorus. It can be used as a food additive.
Description
Sodium hypophosphite (NaPO2H2, also known as sodium phosphinate) is the sodium salt of hypophosphorous acid and is often encountered as the monohydrate, NaPO2H2·H2O. 
Technical Data

Chemical name: Sodium hypophosphite, NaH2PO2

Other names: SODIUM HYPOPHOSPHITE, Phosphinic acid, sodium salt; sodium monophosphate; Hypophosphorous Acid Monosodium Salt; Sodium hypophosphite; Phosphinic Acid Monosodium Salt; Sodium Phosphinate; Fosfinato de sodio; Phosphinate de sodium.

Chemical formula: NaH2PO2.H2O

Purity: 100%

CAS number: 7681-53-0, 10039-56-2 (monohydrate)

Appearance: White crystal

Sodium hypophosphite (NaPO2H2, also known as sodium phosphinate) is the sodium salt of hypophosphorous acid and is often encountered as the monohydrate, NaPO2H2·H2O. It is a solid at room temperature, appearing as odorless white crystals. It is soluble in water, and easily absorbs moisture from the air.

Sodium hypophosphite should be kept in a cool, dry place, isolated from oxidizing materials. It decomposes into phosphine which is irritating to the respiratory tract and disodium phosphate. : 2 NaH2PO2 → PH3 + Na2HPO4

Applications:

  • Sodium hypophosphite is mainly used for electroless nickel plating (Ni-P). With this method, a durable nickel-phosphorus film can coat objects with irregular surfaces, such as in avionics, aviation and the petroleum field.
  • Sodium hypophosphite is capable of reducing nickel ions in solution to metallic nickel on metal substrates as well as on plastic substrates. The latter requires that the substrate is activated with fine particles of palladium. The resulting nickel deposit contains up to 15% phosphorus.
  • It can be used as a food additive.
