Sodium tungstate dihydrate Chemical Properties,Uses,Production

Chemical Properties

white to slightly yellow crystalline powder or

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.

Uses

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

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].
