Hazard Predictions
- Generates gas: Reaction liberates gaseous products and may cause pressurization
- Intense or explosive reaction: Reaction may be particularly intense, violent, or explosive
The combination of chlorosilanes with acetals or hemiacetals (compounds containing hydroxyl groups) may react vigorously, as is documented below:
Reaction of SiCl4 and ethanol is exothermic and evolves toxic HCl gas, which can lead to overpressurization (Skinner, S.J. 1981. Loss Prevention 14:178-180.).
Chlorosilanes react with alcohols to form silyl ethers and HCl gas (Butts, M., et al., 2002. Silicones. Kirk-Othmer Encyclopedia of Chemical Technology. (Online)).
Potential Gas Byproducts
- Hydrogen Chloride (HCl)
- Acid Fumes
