Tungsten trioxide is a starting material for the synthesis of tungstates. Barium tungstate BaWO 4 is used as a x-ray screen phosphors . Alkali metal tungstates, such as lithium tungstate Li 2 WO 4 and cesium tungstate Cs 2 WO 4 , give dense solutions that can be used to separate minerals. [ 1 ]
Ethyl acetate (systematically ethyl ethanoate, commonly abbreviated EtOAc, ETAC or EA) is the organic compound with the formula CH 3 CO 2 CH 2 CH 3, simplified to C 4 H 8 O 2.This flammable, colorless liquid has a characteristic sweet smell (similar to pear drops) and is used in glues, nail polish removers, and the decaffeination process of tea and coffee.
Tungsten has several oxidation states, and therefore oxides: Tungsten(III) oxide; Tungsten(IV) oxide, also known as tungsten dioxide; Tungsten(VI) oxide, also known as tungsten trioxide; Tungsten pentoxide
Silicotungstic acid is used to manufacture ethyl acetate by the alkylation of acetic acid by ethylene: C 2 H 4 + CH 3 CO 2 H → CH 3 CO 2 C 2 H 5. It has also been commercialized for the oxidation of ethylene to acetic acid: [2] C 2 H 4 + O 2 → CH 3 CO 2 H. This route is claimed as a "greener" than methanol carbonylation. The heteropoly acid ...

Tungstic acid refers to hydrated forms of tungsten trioxide, WO 3. Both a monohydrate (WO 3 ·H 2 O) and hemihydrate (WO 3 · 1 / 2 H 2 O) [1] are known. Molecular species akin to sulfuric acid, i.e. (HO) 2 WO 2 are not observed. The solid-state structure of WO 3 ·H 2 O consists of layers of octahedrally coordinated WO 5 (H 2 O) units where 4 ...
The dominant use of sodium tungstate is as an intermediate in the extraction of tungsten from its ores, almost all of which are tungstates. [1] Otherwise sodium tungstate has only niche applications. In organic chemistry, sodium tungstate is used as catalyst for epoxidation of alkenes and oxidation of alcohols into aldehydes or ketones .
2-Ethoxyethanol, also known by the trademark Ethyl cellosolve, is a solvent used widely in commercial and industrial applications. It is a clear, colorless, nearly odorless liquid that is miscible with water, ethanol, diethyl ether, acetone, and ethyl acetate. [3] 2-Ethoxyethanol is manufactured by the reaction of ethylene oxide with ethanol.
