Reactive Group Datasheet


What are reactive groups?

Reactive groups are categories of chemicals that typically react in similar ways because they are similar in their chemical structure. Each substance with a chemical datasheet has been assigned to one or more reactive groups, and CAMEO Chemicals uses the reactive group assignments to make its reactivity predictions. More info about reactivity predictions...

If you can't find a chemical in the database--but you know what reactive group it belongs in--you can add the reactive group to MyChemicals instead in order to see the reactivity predictions.

There are 37 chemical datasheets assigned to this reactive group.


Flammable or pyrophoric.
Chlorosilanes 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.
Poisonous by ingestion and inhalation and a poisonous irritant to the skin, eyes, and mucous membranes. The toxicity is based on that of HCl, which forms by the reaction of chlorosilanes with water.
Other Characteristics
Materials in this group are characterized by a silicon-chlorine bond with various numbers of hydrogen atoms and organics also bonded to the silicon atom. These materials produce HCl in the presence of water/moisture.
Allyltrichlorosilane, methyldichlorosilane, silicon tetrachloride, vinyl trichlorosilane, trimethylchlorosilane, trichlorosilane, propyltrichlorosilane, phenyltrichlorosilane, methyl trichlorosilane.
