Sodium hypophosphite monohydrate Usage And Synthesis

Chemical Properties

White crystals

Uses

Sodium hypophosphite monohydrate is an emulsifier or stabilizer that is a white, odorless, deliquescent granular powder with a saline taste. It is also prepared as colorless, pearly crystalline plates.

Uses

Sodium hypophosphite monohydrate is used for electroless nickel plating agent and water treatment agent. It is also used in petroleum fields. Further, it is used as a food additive. In addition, it reduces nickel ions in solution to metallic nickel on metal substrates as well as on plastic substrates.

Uses

Sodium hypophosphite monohydrate is used for electroless nickel plating. Sodium Hypophosphite is capable of reducing nickel ions in solution to metallic nickel on metal substrates as well as on plastic substrates

Purification Methods

Dissolve it in boiling EtOH, cool and add dry Et2O till all the salt separates. Collect and dry it in vacuum. It is soluble in 1 part of H2O. It liberates PH3 on heating and can ignite spontaneously when heated. The anhydrous salt is soluble in ethylene glycol (33% w/w) and propylene glycol (9.7%) at 25o.
