Trichlorosilane (TCS) is an inorganic compound with the formula HCl 3 Si. It is a colourless, volatile liquid. It is a colourless, volatile liquid. Purified trichlorosilane is the principal precursor to ultrapure silicon in the semiconductor industry.
Silicon tetrachloride and trichlorosilane are intermediates in the production of ultrapure silicon in the semiconductor industry. Chlorosilanes obtained from crude silicon are purified by fractional distillation techniques and then reduced with hydrogen to give silicon of 99.999 999 999 % purity.

They did, however, complete the hydrolysis using dilute Et 2 O/CCl 4 at -10 °C. The purpose of completing the hydrolysis of dichlorosilane is to collect the concentrated hydrolysis products, distill the solution, and retrieve a solution of [H 2 SiO] n oligomers in dichloromethane. [3] These methods were used to obtain cyclic polysiloxanes.

3 C – CCl 3, and chloral HOC – CCl 3. The trichloromethyl group has a significant electronegativity. [citation needed] For this reason, trichloromethyl-substituted acids, such as trichloromethanesulfonic acid, are often stronger than the original. For example, the acidity constant (pK a) of trichloroacetic acid HOOC – CCl
Trichlorophenylsilane is a compound with formula Si(C 6 H 5)Cl 3. Similarly to other alkylchlorosilanes, trichlorophenylsilane is a possible precursor to silicone . It hydrolyses in water to give HCl and phenylsilantriol, with the latter condensating to a polymeric substance.
