Vinyltriethoxysilane

Vinyltriethoxysilane (VTEOS) is a type of organosilicon compound used in a variety of industrial applications. It is a colorless liquid that is soluble in organic solvents and hydrolyzes in the presence of moisture.

Chemical Structure

Vinyltriethoxysilane has the chemical formula C8H18O3Si. It consists of a vinyl group (C2H3) attached to a silicon atom, which is in turn bonded to three ethoxy groups (C2H5O). The silicon atom is the central atom in the molecule, with the vinyl group and ethoxy groups arranged around it.

Properties

Vinyltriethoxysilane is a colorless liquid at room temperature. It has a boiling point of 161°C and a density of 0.93 g/cm³. It is soluble in most organic solvents, but is hydrolyzed by water to form silanol and ethanol.

Applications

Vinyltriethoxysilane is used as a coupling agent in the production of silicone rubber and other silicone-based materials. It is also used as a crosslinking agent in the manufacture of polyethylene and other polymers. In addition, it is used as a surface modifier to improve the adhesion of organic materials to inorganic surfaces.

Safety

Vinyltriethoxysilane is a flammable liquid and its vapors can form explosive mixtures with air. It can cause irritation to the eyes, skin, and respiratory tract. It should be handled with care, using appropriate personal protective equipment.
