High Purite 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 scent. it's going to decompose with water and dissolve in carbon disulfide, carbon tetrachloride, chloroform, benzene, and lots of others. flammable, can spontaneously ignite in the air. poisonous!
It may undergo an addition reaction with olefins.
The hydrosilylation reaction of ethylene is as follows: cl3si-h + h2c=ch2 → cl3si-ch2-ch3 . the response is catalyzed through manner of catalysts which includes h2ptcl6, co2(co)eight, ni(cod)2, nicl2(pph3)2 or rhcl(pph3)three.

Prepare
The dried silicon powder reacts with the dried hydrogen chloride gasoline at 340°c in a chlorination fluidized bed furnace, and the generated crude trichlorosilane is separated into silicon tetrachloride by means of the usage of a moist dirt collector and a pipe bundle condenser distillation tower, and then condensed to reap the finished product. the product also can be obtained by means of the use of the response of ferrosilicon and hcl.
