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.
Dichlorosilane, or DCS as it is commonly known, is a chemical compound with the formula H 2 SiCl 2. In its major use, it is mixed with ammonia (NH 3) in LPCVD chambers to grow silicon nitride in semiconductor processing. A higher concentration of DCS·NH 3 (i.e. 16:1), usually results in lower stress nitride films.
In organic chemistry, a methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms, having chemical formula CH 3 (whereas normal methane has the formula CH 4). In formulas, the group is often abbreviated as Me. This hydrocarbon group occurs in many organic compounds. It is a very stable group in ...
The chemical formula of PDMS is CH 3 [Si(CH 3) 2 O] n Si(CH 3) 3, where n is the number of repeating monomer [Si(CH 3) 2 O] units. [4] Industrial synthesis can begin from dimethyldichlorosilane and water by the following net reaction: n Si(CH 3) 2 Cl 2 + (n+1) H 2 O → HO[Si(CH 3) 2 O] n H + 2n HCl. The polymerization reaction evolves ...
Methyltrichlorosilane, also known as trichloromethylsilane, is a monomer and organosilicon compound with the formula CH 3 SiCl 3. It is a colorless liquid with a sharp odor similar to that of hydrochloric acid. As methyltrichlorosilane is a reactive compound, it is mainly used a precursor for forming various cross-linked siloxane polymers.
A trimethylsilyl group (abbreviated TMS) is a functional group in organic chemistry.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.
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. It is widely used in organic chemistry.
Trimethylsilanol (TMS) is an organosilicon compound with the formula (CH 3) 3 SiOH. The Si centre bears three methyl groups and one hydroxyl group. It is a colourless volatile liquid.
