Product Description

Product Description

High Purity Tetrapropoxysilane / tetrapropyl silicate CAS 682-01-9
T

Tetrapropoxysilane, also known as silicon tetrapropoxide or tetrapropyl orthosilicate (TPOS), is a chemical compound with the molecular formula Si(C3H7O)4. It is a colorless liquid that is used as a precursor in the synthesis of various silicon-containing materials, such as silica, silicon dioxide, and silicon carbide.

Tetrapropoxysilane is highly reactive due to the presence of four highly polarizable propoxy groups attached to the silicon atom. It undergoes hydrolysis in the presence of water to form silicic acid and propanol:
