Gas Introduction
Dichlorosilane is a colorless toxic gas with a pungent, suffocating odor and corrosiveness at room temperature and pressure. It is flammable in the air and can spontaneously ignite above 44 ℃. After combustion and oxidation, it generates hydrogen chloride and silicon oxide. When heated above 100 ℃, it will decompose on its own and generate hydrogen chloride, chlorine, hydrogen, and amorphous silicon. It will also decompose on its own when subjected to strong impact. Generate corrosive smoke in humid air. Hydrolysis upon contact with water produces hydrochloric acid and polysiloxane (SiH2O) 4. Soluble in benzene, ether, and carbon tetrachloride. Reacts with alkali, ethanol, and acetone. Even when exposed to small amounts of halogens or other oxidants, intense reactions can occur. Form addition compounds with trialkylamine and pyridine. Reacts with antimony trifluoride to produce fluorosilane.
