We are the most preeminent manufacturer, exporter and supplier of Sodium Tungstate in India. Sodium tungstate is the inorganic compound with the formula Na2WO4. This white, water-soluble solid is the sodium salt of tungstic acid. It is useful as a source of tungsten for chemical synthesis. It is an intermediate in the conversion of tungsten ores to the metal.
Sodium Tungstate is also known(synonyms)Disodium tungstate, Na2WO4, sodium tetraoxotungstate (VI), Sodium tungstate (VI), Sodium tungsten oxide, Sodium wolframite, Tungstic acid, disodium salt.
Applications / Usage :
In organic chemistry, sodium tungstate is used as catalyst for epoxidation of alkenes and oxidation of alcohols into aldehydes or ketones. It with hydrogen peroxide for the oxidation of secondary amines to nitrones. It has a role as a reagent. It contains a tungstate.
