Sodium perborate Chemical Properties,Usage,Production

Chemical Properties

Sodium perborate, anhydrous, NaB03 is a white,amorphous powder of unknown constitution containing active oxygen that evolves oxygen gas when dissolved in water,and is hygroscopic. Derived by heating sodium perborate tetrahydrate. Used as a denture cleaner and oxygen source.
Sodium perborate, monohydrate, NaB03·H20 , better represented as Na2(B2(02)2(OH)4) is a white, amorphous powder that is rapidly soluble in water givinga solution of H202 and sodium borated.Derived by partial dehydration of sodium perborate tetrahydrate. Used as a denture cleaner and bleaching agent.

Chemical Properties

Colourless, prismatic crystals or white or almost white powder, stable in the crystalline form.

Uses

Sodium perborate is the most widely used solid peroxygen compound. Commercially, it is available as a tetrahydrate and a monohydrate. The tetrahydrate is produced by treating a borax solution with hydrogen peroxide and sodium hydroxide.

Uses

Antiseptic.
