Tetraethyl orthosilicate Usage And Synthesis
Ethyl silicate Ethyl silicate is also known as Tetraethyl orthosilicate,colorless, transparent liquid with special smell.
Chemical Properties Ethyl silicate is a flammable, colourless liquid with a mild, sweet, alcohol-like odour. Exposure to ethyl silicate can occur through inhalation, ingestion, and eye or skin contact. It is practically insoluble in water, soluble in alcohol, and slightly soluble in benzene.
Tetraethyl orthosilicate is Used as insulating materials in electronic industry, also used for optical glass processing and used as coagulants.

Tetraethyl orthosilicate is the chemical compound with the formula Si(OC2H5)4. Often abbreviated TEOS, it is a colorless liquid that degrades in water. TEOS is the ethyl ether of orthosilicic acid, Si(OH)4. It is a prototypical alkoxide.
TEOS is a tetrahedral molecule. Like its many analogues, TEOS is prepared by alcoholysis of silicon tetrachloride:; SiCl4 + 4 EtOH → Si(OEt)4 + 4 HCl; where Et = C2H5.
