Dichlorodiphenylsilane Usage And Synthesis

Chemical Properties

Diphenyldichlorosilane is a colorless liquid with a pungent odor. It will burn though it may require some effort to ignite. It is decomposed by water to hydrochloric acid with evolution of heat. It is corrosive to metals and tissue.

Uses

Dichlorodiphenylsilane is a silane based surface modifier, and a precursor which can be used in the synthesis of silica based materials. It is used to modify the surface by providing toughness, durability and resistance to shock. It can be used in the synthesis of a host material for the fabrication of blue phosphorescent organic light emitting diodes (OLEDs).

Reactivity Profile

Chlorosilanes, such as Dichlorodiphenylsilane, 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.

Health Hazard

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

Flammability and Explosibility

Notclassified

Safety Profile

A poison irritant to skin, eyes, and mucous membranes. See also CHLOROSILANES. Can react vigorously with oxidizing materials. When heated to decomposition or on contact with acid or acid fumes it emits toxic fumes of Cl-.
