Products Description of Trichlorosilane CAS#：10025-78-2
Trichlorosilane is pungent stench flowable volatile colorless liquid at room temperature and pressure. It is highly flammable in air, it also has the risk of fire at below-18 ℃, when meets open fire, it burns strongly with red flames and white smoke, and SiO2, HCl and Cl2 can generate: SiHCl3 + O2 → SiO2 + HCl + Cl2; the vapor of three chlorosilane and air can form a wide range of concentrations of explosive gas mixture, and it can cause violent explosion when be heated. The thermal stability is better than dichlorosilane, it can decompose into toxic fumes chloride (HCl), Cl2 and Si at 900℃. When meets moisture, it can generate smoke, it can react violently with water: 2SiHCl3 + 3H2O → (HSiO) 2O + 6HCl; It can decompose in lye and release hydrogen: SiHCl3 + 3NaOH + H2O → Si (OH) 4 + 3NaCl + H2; and when it contacts oxidative substances, explosive reaction can occur. The reaction with acetylene, hydrocarbons and other organic hydrocarbons can produce chlorosilane: SiHCl3 + CH≡CH → CH2CHSiCl3, SiHCl3 + CH2 = CH2 → CH3CH2SiCl3; In the presence of lithium aluminum hydride, lithium borohydride, SiHCl3 can be reduced to silane. When the container is subjected to strong shock, liquid SiHCl3 will fire. It is soluble in benzene, ether etc.. Anhydrous trichlorosilane can not corrode iron and stainless steel, but in the presence of moisture, it can corrode most metals.
