Melting point: −126.6 °C (−195.9 °F; 146.6 K) ... Trichlorosilane (TCS) is an inorganic compound with the formula HCl 3 Si. It is a colourless, volatile liquid.
Methyltrichlorosilane results from the direct process of chloromethane with elemental silicon in the presence of a copper catalyst, usually at a temperature of at least 250 °C. [ 1 ] 2 CH 3 Cl + Si → (CH 3 ) 4−n SiCl n + other products
Trichlorosilane: Chemical formula: H Si Cl 3: Appearance: Colourless liquid: Physical. Molar mass: 135.5 g/mol: Melting point: 146 K (-127 °C) Boiling point: 305 K ...
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.
Melting point: −122 °C (−188 °F; 151 K) ... In its major use, ... Disproportionation of trichlorosilane is the preferred route. [4]
Carbosilanes are polymeric silanes with alternating Si-C bonds. Chlorosilanes have Si-Cl bonds. The dominant examples come from the Direct process, i.e., (CH 3) 4-x SiCl x. Another important member is trichlorosilane (SiHCl 3). Organosilanes are a class of charge-neutral organosilicon compounds. Example: tetramethylsilane (Si(CH 3) 4)
The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.
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.
