N-HEXADECYLTRICHLOROSILANE Chemical Properties,Usage,Production

Chemical Properties

Colorless to yellow liquid.

Uses

Intermediate for silicones.

General Description

N-HEXADECYLTRICHLOROSILANE is a colorless to yellow liquid with a pungent odor. Material will burn though N-HEXADECYLTRICHLOROSILANE may require some effort to ignite. N-HEXADECYLTRICHLOROSILANE is decomposed by moisture or water to hydrochloric acid with evolution of heat. N-HEXADECYLTRICHLOROSILANE is corrosive to metals and tissue.

Air & Water Reactions

Reacts violently with water, steam, moist air, alcohols, acetone, light metals with generation of heat and combustible (H2) and corrosive (HCl) gases. On contact with air N-HEXADECYLTRICHLOROSILANE gives off HCl gas. REF [Handling Chemicals Safely, 1980 p. 924]. Fumes in air.

Reactivity Profile

Chlorosilanes, such as N-HEXADECYLTRICHLOROSILANE, 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

Strong irritant. Combustible. Evolves hydrogen chloride in the presence of moisture.

Health Hazard

TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Contact with molten substance may cause severe burns to skin and eyes. 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

Combustible material: may burn but does not ignite readily. Substance will react with water (some violently) releasing flammable, toxic or corrosive gases and runoff. When heated, vapors may 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. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water.

Flammability and Explosibility

Non flammable
