Hazard Predictions

• Flammable: Reaction products may be flammable
• Generates gas: Reaction liberates gaseous products and may cause pressurization
• Generates heat: Exothermic reaction at ambient temperatures (releases heat)

Chlorosilanes may release toxic HCl gas on contact with protic compounds, including amines; chlorosilanes possessing Si-H bonds may produce flammable H2 gas instead (Arkles, B. 2000. Silicon Compounds, Silanes. In Kirk-Othmer Encyclopedia of Chemical Technology. John Wiley & Sons, Inc. (Online)).

Dichlorosilane reacts exothermically with primary and secondary amines. It may disproportionate under the influence of heat or catalysis, such as amines, to form mixtures of silane, monochlorosilane, trichlorosilane, and silicon tetrachloride. These mixtures may be pyrophoric (Dichlorosilane, MSDS No. 1044, Air Products and 365bet娱乐 Inc., Allentown, PA, September 1998).

Trichlorosilane and trichloropropylsilane are incompatible with aliphatic amines and alkanolamines, and react violently with ammonia (Pohanish, Richard P.; Greene, Stanley A. (2009). Wiley Guide to Chemical Incompatibilities (3rd Edition). John Wiley & Sons. p 1034).

Vinyl trichlorosilane reacts violently with amines, including ammonia (Pohanish, Richard P.; Greene, Stanley A. (2009). Wiley Guide to Chemical Incompatibilities (3rd Edition). John Wiley & Sons. p 1074).
