Sodium tungstate dihydrate Chemical Properties,Usage,Production

Chemical Properties

white to slightly yellow crystalline powder or

Uses

Sodium tungstate dihydrate is currently being investigated as a potential therapy for obesity. Sodium tungstate dihydrate is also an inhibitor of acid phosphatases.

Uses

Sodium tungstate dihydrate may be used in the preparation of aqueous sols of tungsten oxide dihydrate.

Uses

Fireproofing and waterproofing fabrics; preparing complex Compounds such as phosphotungstate and silicotungstate; as a protective colloid in biological development methods; precipitant for alkaloids; catalyst in oxidation reactions; corrosion inhibitor for steel.

Definition

ChEBI: A hydrate that is the dihydrate form of sodium tungstate. Combines with hydrogen peroxide for the oxidation of secondary amines to nitrones

General Description

Sodium tungstate dihydrate is a sodium salt of tungstic acid, which occurs as white colorless crystals.

Purification Methods

The salt crystallises from hot water (0.8mL/g) on cooling to 0o. [Grüttner & Jender in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol II p 1727 1965].
