Dimethyldichlorosilane is a tetrahedral organosilicon compound with the formula Si(CH 3) 2 Cl 2. At room temperature it is a colorless liquid that readily reacts with water to form both linear and cyclic Si-O chains. Dimethyldichlorosilane is made on an industrial scale as the principal precursor to dimethylsilicone and polysilane compounds.
[3] [5] A large-scale hydrolysis was done in a mixed ether/alkane solvent system at 0 °C, which gave a mixture of volatile and nonvolatile [H 2 SiO] n. Fischer and Kiegsmann attempted the hydrolysis of dichlorosilane in hexane, using NiCl 2 ⋅6H 2 O as the water source, but the system failed. [ 3 ]
2 ((CH 3) 3 SiCl + H 2 O → [(CH 3) 3 Si] 2 O + 2 HCl. The analogous reaction of dimethyldichlorosilane gives siloxane polymers or rings: n (CH 3) 2 SiCl 2 + n H 2 O → [(CH 3) 2 SiO] n + 2n HCl. Many compounds containing Si-Cl bonds can be converted to hydrides using lithium aluminium hydride, This kind of conversion was demonstrated for the ...
MeSiCl 3 + 3 H 2 O → MeSi(OH) 3 + 3 HCl. The silanol is unstable and will eventually condense to give a polymer network: MeSi(OH) 3 → MeSiO 1.5 + 1.5 H 2 O. Methyltrichlorosilane undergoes alcoholysis (reaction with alcohol) to give alkoxysilanes. Methanol converts it to trimethoxymethylsilane: MeSiCl 3 + 3 CH 3 OH → MeSi(OCH 3) 3 + 3 HCl
This group consists of three methyl groups bonded to a silicon atom [−Si(CH 3) 3], which is in turn bonded to the rest of a molecule. This structural group is characterized by chemical inertness and a large molecular volume , which makes it useful in a number of applications.
Trimethylsilyl chloride, also known as chlorotrimethylsilane is an organosilicon compound (silyl halide), with the formula (CH 3) 3 SiCl, often abbreviated Me 3 SiCl or TMSCl. It is a colourless volatile liquid that is stable in the absence of water.
The heat of evaporation is 45.64 kJ·mol −1, the evaporation entropy 123 J·K −1 ·mol −1. [2] The vapor pressure function according to Antoine is obtained as log 10 (P/1 bar) = A − B/(T + C) (P in bar, T in K) with A = 5.44591, B = 1767.766 K and C = −44.888 K in a temperature range from 291 K to 358 K. [ 2 ] Below the melting point ...
