Ethylphenyldichlorosilane

Chemical Properties

Colorless liquid that fumes strongly in moist air.

General Description

Ethylphenyldichlorosilane is a colorless liquid with a pungent odor. Ethylphenyldichlorosilane is decomposed by water to hydrochloric acid with evolution of heat. Ethylphenyldichlorosilane is corrosive to metals and tissue.

Air & Water Reactions

Reacts vigorously with water to form hydrogen chloride(hydrochloric acid)

Reactivity Profile

Chlorosilanes, such as Ethylphenyldichlorosilane, are compounds in which silicon is bonded to from one to four chlorine atoms with other bonds to hydrogen and/or alkyl groups. Chlorosilanes react with water, moist air, or steam to produce heat and toxic, corrosive fumes of hydrogen chloride. They may also produce flammable gaseous H2. They can serve as chlorination agents. Chlorosilanes react vigorously with both organic and inorganic acids and with bases to generate toxic or flammable gases. Special Hazards of Combustion Products: Toxic hydrogen chloride and phosgene fumes may be formed.

Hazard

Toxic by inhalation and ingestion, strong irritant to eyes and skin.

Health Hazard

Inhalation irritates nose and throat. Contact with liquid causes severe burns of eyes and skin. Ingestion causes severe burns of mouth and stomach.

Safety Profile

Poison by ingestion and inhalation. A poison irritant to skin, eyes, and mucous membranes. Corrosive. Will react with water or steam to produce toxic and corrosive fumes. Can react with oxidizing materials. When heated to decomposition it emits toxic fumes of Cl and phenol. See also CHLOROSILANES.

Potential Exposure

Used in the manufacture of silicone polymers

Shipping

UN2435 Ethylphenyldichlorosilane, Hazard class: 8; Labels: 8-Corrosive material.

Incompatibilities

A strong reducing agent. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, and epoxides. Chlorosilanes react vigorously with bases and both organic and inorganic acids generating toxic and/or flammable gases. Chlorosilanes react with water, moist air, or steam to produce heat and toxic, corrosive fumes of hydrogen chloride. They may also produce flammable gaseous hydrogen.
