Hazard Predictions
- Potentially hazardous: May be hazardous but unknown
When combined, strong oxidizers and chlorosilanes may react with intensity, as shown in the examples below. However, no specific evidence was found for a hazardous reaction between weak oxidizers and chlorosilanes. Because of the nature of the members of the Weak Oxidizing Agents group we would not expect reaction kinetics to yield hazardous conditions. We urge chemists to perform testing to ensure that hazards do not occur under conditions appropriate to the scenario.
Dichlorosilane may ignite on contact with nitrate or nitrite salts under basic conditions (Urben, P.G. 1995. Bretherick's Handbook of Reactive Chemical Hazards, 5th Edition. Oxford: Butterworth-Heinemann. pp. 1314.; Britton, L. G. (1990). Plant/Oper. Progr., 9 (1), 16).
When heated, the vapours of the higher chlorosilanes (hexachlorodisilane to dodecachloropentasilane) ignite in air. Other halo- and haloalkyl-silanes ignite without heating or have low flash points (Schumb, W. C. et al., Inorg. Synth., 1939, 1, 46).
Vinyl trichlorosilane is incompatible with nitrogen oxides. (Pohanish, Richard P. (2004). HazMat Data - For First Response, Transportation, Storage, and Security (2nd Edition). John Wiley & Sons).
