Tetraethyl orthosilicate
Description
Tetraethyl orthosilicate CAS No 78-10-4
Tetraethyl orthosilicate 78-10-4 is the chemical compound with the formula Si(OC2H5)4. Often abbreviated TEOS, this molecule consists of four ethyl groups attached to SiO44− ion, which is called orthosilicate. As an ion in solution, orthosilicate does not exist. Alternatively, TEOS can be considered to be the ethyl ester of orthosilicic acid, Si(OH)4.
Also, it is a prototypical alkoxide. TEOS is mainly used as a crosslinking agent in silicone polymers and as a precursor to silicon dioxide in the semiconductor industry. TEOS is also used as the silica source for synthesis of zeolites. Other applications include coatings for carpets and other objects. In addition, TEOS is used in the production of aerogel. These applications exploit the reactivity of the Si-OR bonds.
