Molecular formula:SiHCl3。
Physical and chemical properties:
The dried silica powder is reacted with dry hydrogen chloride gas in a chlorination boiler at 340°C, and the resulting crude trichlorosilane is separated by a wet precipitator and a tube condenser dedistillation column, and then condensed to obtain the finished product. The product can also be obtained by the reaction of ferrosilicon and HCl.
Density 1.342g/cm3, boiling point 31.8°C, melting point -126.6°C, flash point -27°C, explosion limit 1.2-90.5%, vapor pressure 0.66bar(20°C)
A colorless liquid with a pungent odor. Decomposition in water, soluble in carbon disulfide, carbon tetrachloride, chloroform, benzene and so on. Flammable and can spontaneously ignite in air. Toxic!
Production usage：It is used as a raw material for organic silicon compounds, and is also the basic raw material for the production of polysilicon
