Medium Carbon Trichlorosilane
The dried silicon powder reacts with the dried hydrogen chloride gas at 340°C in a chlorination fluidized bed furnace, and the generated crude trichlorosilane is separated into silicon tetrachloride by a wet dust collector and a pipe bundle condenser distillation tower, and then condensed to obtain the finished product. The product can also be obtained by the reaction of ferrosilicon and HCl.
Colorless liquid with stinky smell. it will decompose with water and dissolve in carbon disulfide, carbon tetrachloride, chloroform, benzene, and many others. flammable, can spontaneously ignite inside the air. poisonous!
