Reactive Group:

Chlorosilanes

Reactivity Alerts:

Highly Flammable

Reactivity Profile:

Chlorosilanes, such as DICHLOROSILANE, 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.

Physical Dangers:

The gas is heavier than air and may travel along the ground; distant ignition possible.
