Hexyltrichlorosilane is a colorless liquid with a pungent odor. It is decomposed by moist air or water to hydrochloric acid with evolution of heat. It is corrosive to metals and tissue. It is used as a chemical intermediate.

All containers, pipes, apparatus, installations, and structures used for manufacture, storage, transport, or use of these substances must be of material resistant to corrosive substances or be protected by suitable coatings All containers or receptacles should be clearly labelled to indicate their contents and should bear the danger symbol for corrosives. /Corrosive substances/

Flammable; emits toxic hydrogen chloride gas in water; emits toxic gas in fire

Decomposes in water|Fumes strongly in moist air.|The reaction of organosilanes with halogens and halogen compounds usually proceeds in good yield through cleavage of the Si--H bond and formation of the silicon-halogen bond. Reaction with fluorine, however, does not proceed satisfactorily because of cleavage of not only the Si--H but also C--Si and C--H bonds. Direct halogenation with chlorination, bromine, and iodine proceeds smoothly, however. /Organosilanes/

Fumes in air. 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 it gives off HCl gas [Handling Chemicals Safely, 1980 p. 924]. Hexyltrichlorosilane reacts vigorously with water to generate gaseous HCl.Based on a scenario where the chemical is spilled into an excess of water (at least 5 fold excess of water), half of the maximum theoretical yield of Hydrogen Chloride gas will be created in 2.5 minutes.

Chlorosilanes

Water-Reactive

Chlorosilanes, such as HEXYLTRICHLOROSILANE, 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.
