The reaction can be noticed on exposure of the liquid to air, as SiCl 4 vapour produces fumes as it reacts with moisture to give a cloud-like aerosol of silica and hydrochloric acid. [6] In contrast, carbon tetrachloride is not readily hydrolyzed. With alcohols it reacts to give orthosilicate esters: SiCl 4 + 4 ROH → Si(OR) 4 + 4 HCl
In inorganic chemistry, chlorosilanes are a group of reactive, chlorine-containing chemical compounds, related to silane (SiH 4) and used in many chemical processes. Each such chemical has at least one silicon-chlorine (Si−Cl) bond. Trichlorosilane is produced on the largest scale. The parent chlorosilane is silicon tetrachloride (SiCl 4). [1]
The pyrolysis of SiBr 4 does have the advantage of depositing silicon at faster rates than that of SiCl 4, however SiCl 4 is usually preferred due to its availability in high purity. [13] Pyrolysis of SiBr 4 followed by treatment with ammonia yields silicon nitride (Si 3 N 4 ) coatings, a hard compound used for ceramics, sealants, and the ...
4-x SiCl x. These chlorides are produced by the "Direct process", which entails the reaction of methyl chloride with a silicon-copper alloy. The main and most sought-after product is dimethyldichlorosilane: 2 CH 3 Cl + Si → (CH 3) 2 SiCl 2. A variety of other products are obtained, including trimethylsilyl chloride and methyltrichlorosilane ...
Silicon carbide is rapidly attacked by chlorine gas, which forms SiCl 4 and carbon at 100 °C and SiCl 4 and CCl 4 at 1000 °C. It is mostly used as an abrasive and a refractory material, as it is chemically stable and very strong, and it fractures to form a very sharp cutting edge.
Nanowires based on silicon and manganese can be synthesised from Mn(CO) 5 SiCl 3 forming nanowires based on Mn 19 Si 33. [ 14 ] or grown on a silicon surface [ 15 ] [ 16 ] [ 17 ] MnSi 1.73 was investigated as thermoelectric material [ 18 ] and as an optoelectronic thin film. [ 19 ]
Silicon tetrachloride – SiCl 4; Silver chloride – AgCl; Silver perchlorate – AgClO 4; Sodium chlorate – NaClO 3; Sodium chloride (table salt, rock salt) – NaCl;
Via hydrosilylation, trichlorosilane is a precursor to other useful organosilicon compounds: . RCH=CH 2 + HSiCl 3 → RCH 2 CH 2 SiCl 3. Some useful products of this or similar reactions include octadecyltrichlorosilane (OTS), perfluoroctyltrichlorosilane (PFOTCS), and perfluorodecyltrichlorosilane (FDTS).
