Chemical Properties
Colorless clear liquid
Uses
Intermediate for silicones.
General Description
A colorless liquid with a pungent odor. Flash point 100°F. Corrosive to metals and tissue.
Reactivity Profile
PROPYL TRICHLOROSILANE reacts violently with water, steam, moist air, alcohols, acetone, and light metals with generation of heat and flammable (H2) and corrosive (HCl) gases.
Hazard
Flammable, moderate fire risk. Strong irri-
tant.
Health Hazard
TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Bromoacetates and chloroacetates are extremely irritating/lachrymators. Reaction with water or moist air will release toxic, corrosive or flammable gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Fire Hazard
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapors may travel to source of ignition and flash back. Substance will react with water (some violently) releasing flammable, toxic or corrosive gases and runoff. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water.
Flammability and Explosibility
Flammable
Safety Profile
Confirmed carcinogen with experimental carcinogenic, neoplastigenic, and tumorigenic data. Poison by intraperitoneal route. Moderately toxic by ingestion. Human systemic effects: agranulocytosis, hepatitis, jaundice. Human teratogenic effects by ingestion:developmental abnormalities of the endocrine system and changes in newborn viability. Human and experimental teratogenic and reproductive effects. Human mutation data reported. When heated to decomposition it emits very toxic fumes of SOx, and NOx. See also MERCAPTANS.
