Ethyltrichlorosilane Chemical Properties,Uses,Production
Chemical Properties
Ethyl trichlorosilane is a colorless liquid with an irritating odor
Chemical Properties
clear colorless liquid
Uses
Intermediate for silicones.
Production Methods
Manufactured by reaction of ethylene and trichlorosilane in the presence of a peroxide catalyst.
General Description
A colorless fuming liquid with a pungent odor. Flash point 57°F. Boiling point 211.1°F (99.5°C). Vapor and liquid may cause burns. Denser than water. Vapors heavier than air.
Reactivity Profile
Chlorosilanes, such as Ethyltrichlorosilane, 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.
Hazard
Flammable, dangerous fire risk, may form explosive mixture with air. A strong irritant.
Health Hazard
Vapor and liquid cause burns. Do not inhale or expose eyes to vapor. Vapor may damage eyes even if not immediately painful.
Fire Hazard
Trichloroethylsilane may form explosive mixtures with air. Its vapors are heavier than air and may travel a considerable distance to a source of ignition and flash back. Form toxic and corrosive fumes including phosgene when heated to decomposition and hydrochloric acid in presence of water. Will react with water or steam to produce heat and toxic and corrosive fumes. Will react vigorously with oxidizing materials. Unstable, avoid decomposing heat.
Flammability and Explosibility
Highly flammable
Safety Profile
Poison by inhalation and intraperitoneal routes. Moderately toxic by ingestion. A skin and severe eye irritant. A very dangerous fire hazard when exposed to heat, flame, or oxidizers; will react with water or steam to produce heat and toxic and corrosive fumes; can react vigorously with oxidizing materials. To fight fire, use CO2, dry chemical. When heated to decom position it emits highly toxic fumes of Cl and phosgene. See also CHLOROSILANES.
Potential Exposure
Used in the manufacture of silicone polymers.
Shipping
UN1196 Ethyltrichlorosilane, Hazard Class: 3; Labels: 3-Flammable liquid, 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. Attacks metals in the presence of moisture.
