Trichlorosilane Chemical Properties,Uses,Production
Chemical Properties
Clear liquid with acrid odor of hydrogen chloride. soluble in carbon disulfide, carbon tetrachloride, chloroform, benzene, etc.
Uses
Trichlorosilane is used in process of hydrosilylation. It is also used for reductive hydrazination which is a high yielding method for preparation of 1,1-disubstituted hydrazines.
General Description
A colorless fuming liquid with a pungent odor. Flash point 7°F. Vapor and liquid cause burns. More dense than water. Vapors are heavier than air.
Air & Water Reactions
Highly flammable. Ignites spontaneously in air [NFPA, 1991]. Reacts violently with water, steam, moisture in air to generate heat and flammable (H2) and corrosive (HCl) gases. [Handling Chemicals Safely 1980. p. 924].
Reactivity Profile
Trichlorosilane reacts with alcohols, acetone, light metals with generation of heat and combustible (H2) and corrosive (HCl) gases [Handling Chemicals Safely 1980. p. 924].
Health Hazard
Inhalation causes severe irritation of respiratory system. Liquid causes severe burns of eyes and skin. Ingestion causes severe burns of mouth and stomach.
Safety Profile
Moderately toxic by ingestion and inhalation. A corrosive irritant to skin, eyes, and mucous membranes. A very dangerous fire hazard when exposed to heat, flame, or by chemical reaction. May be ignited by spark or impact. Spontaneously flammable in air. Explosive reaction with acetonitrile + diphenyl sulfoxide. 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 decomposition it emits toxic fumes of Cl-. See also CHLOROSILANES.
