75-79-6 Usage

Chemical Properties

Colorless clear liquid

Physical properties

bp 66 °C; d 1.273 g cm?3.

Uses

Different sources of media describe the Uses of 75-79-6 differently. You can refer to the following data:
1. Methyltrichlorosilane is used in production of methyl silicone resins, its vapor reacts with water on surfaces to give a thin layer of methylpolysiloxane which make it a water-repellent film. A combination of methyltrichlorosilane and sodium iodide can be used to cleave carbon-oxygen bonds such as methyl ethers. It is used as a precursor for forming various cross-linked siloxane polymers. Trichloromethylsilane is the starting material for the production of pure silicon for manufacture of semiconductors and optical fibers.
2. Methyltrichlorosilane is widely used as precursor to organosilicon compounds; silylating agent and Lewis acid. MeSiCl3 is an effective Lewis acid in the condensation of carboxylic acids with alcohols and amines.

Production Methods

Produced by Grignard reaction of silicon tetrachloride and methylmagnesium chloride.

General Description

A colorless fuming liquid with a pungent odor. Flash point 8°F. Vapor and liquid may cause burns. Denser than water. Vapors are heavier than air.

Reactivity Profile

Chlorosilanes, such as Methyltrichlorosilane, are compounds in which silicon is bonded to from one to four chlorine atoms with other bonds to hydrogen and/or alkyl groups. Chlorosilanes react with water, moist air, or steam to produce heat and toxic, corrosive fumes of hydrogen chloride. They may also produce flammable gaseous H2. They can serve as chlorination agents. Chlorosilanes react vigorously with both organic and inorganic acids and with bases to generate toxic or flammable gases.

Hazard

Flammable, dangerous fire risk, may formexplosive mixture with air. Strong irritant.

Health Hazard

As with other chlorosilanes, acute exposures may be highly toxic and may cause death or permanent injury after very short exposures to small quantitites. Chronic exposures may be moderately toxic and involve irreversible and reversible changes. Skin contact may produce severe burns with pain and risk of secondary infections. Ingestion may produce oral, esophageal, and stomach burns, intensity will vary from mild to very severe, gastrointestinal damage is rare but may occur.

Fire Hazard

Toxic hydrogen chloride and phosgene gases may form in fires. Reacts with water or steam to form hydrochloric acid. Vapor forms flammable mixture with air. May form explosive mixture in air. Avoid contact with water or moist air.

Safety Profile

Poison by inhalation and intraperitoneal routes. Moderately toxic by ingestion. A severe irritant to skin, eyes, and mucous membranes. Flammable when exposed to heat or flame; can react vigorously with oxidizing materials. When heated to decomposition it emits toxic fumes of Cl-.

Purification Methods

Methyl trichlorosilane [75-79-6] M 149.5, b 13,7o/101mm, 64.3o/710.8mm, 65.5o/745mm, 6 6 . 1o/atm, d 4 1.263, n D If very pure, distil it before use. 20 1.4110. The purity is checked by NMR ( in MeCN is 13.14ppm with respect to Me4Si). Possible contaminants are other silanes which can be removed by fractional distillation through a Stedman column (p 11) of >72 theoretical plates with total reflux and 0.35% take-off. This apparatus should be under N2 gas at a rate of 12 bubbles/minute fed into the line using an Hg manometer to control the pressure. It is sensitive to H2O. [Gillam et al. J Am Chem Soc 73 4252 1951, Olah et al. J Org Chem 48 3667 1983, Beilstein 4 IV 4212.]

Check Digit Verification of cas no

The CAS Registry Mumber 75-79-6 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 7 and 5 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 75-79:
(4*7)+(3*5)+(2*7)+(1*9)=66
66 % 10 = 6
So 75-79-6 is a valid CAS Registry Number.

Unexpected disproportionation of tetramethylethylenediamine-supported perchlorodisilane Cl3SiSiCl3

Tillmann, Jan,Meyer-Wegner, Frank,Nadj, Andor,Becker-Baldus, Johanna,Sinke, Tanja,Bolte, Michael,Holthausen, Max C.,Wagner, Matthias,Lerner, Hans-Wolfram

, p. 8599 - 8606 (2012)

The addition compound Cl3SiSiCl3·TMEDA was formed quantitatively by treatment of Cl3SiSiCl3 with tetramethylethylenediamine (TMEDA) in pentane at room temperature. The crystal structure of Cl3SiSiCl3·TMEDA displays one tetrahedrally and one octahedrally bonded Si atom (monoclinic, P2 1/n). 29Si CP/MAS NMR spectroscopy confirms this structure. Density functional theory (DFT) calculations have shown that the structure of the meridional isomer of Cl3SiSiCl3· TMEDA is 6.3 kcal lower in energy than that of facial coordinate species. Dissolving of Cl3SiSiCl3·TMEDA in CH 2Cl2 resulted in an immediate reaction by which oligochlorosilanes SinCl2n (n = 4, 6, 8, 10; precipitate) and the Cl--complexed dianions [SinCl2n+2] 2- (n = 6, 8, 10, 12; CH2Cl2 extract) were formed. The constitutions of these compounds were confirmed by MALDI mass spectrometry. Additionally, single crystals of [Me3NCH 2CH2NMe2]2[Si6Cl 14] and [Me3NCH2CH2NMe 2]2[Si8Cl18] were obtained from the CH2Cl2 extract. We found that Cl3SiSiCl 3·TMEDA reacts with MeCl, forming MeSiCl3 and the products that had been formed in the reaction of Cl3SiSiCl 3·TMEDA with CH2Cl2. X-ray structure analysis indicates that the structures of [Me3NCH2CH 2NMe2]2[Si6Cl14] (monoclinic, P21/n) and [Me3NCH2CH 2NMe2]2[Si8Cl18] (monoclinic, P21/n) contain dianions adopting an "inverse sandwich" structure with inverse polarity and [Me3NCH 2CH2NMe2]+ as countercations. Single crystals of SiCl4·TMEDA (monoclinic, Cc) could be isolated by thermolysis reaction of Cl3SiSiCl3·TMEDA (50 °C) in tetrahydrofuran (THF).

A General and Selective Synthesis of Methylmonochlorosilanes from Di-, Tri-, and Tetrachlorosilanes

Naganawa, Yuki,Nakajima, Yumiko,Sakamoto, Kei

supporting information, p. 601 - 606 (2021/01/13)

Direct catalytic transformation of chlorosilanes into organosilicon compounds remains challenging due to difficulty in cleaving the strong Si-Cl bond(s). We herein report the palladium-catalyzed cross-coupling reaction of chlorosilanes with organoaluminum reagents. A combination of [Pd(C3H5)Cl]2 and DavePhos ligand catalyzed the selective methylation of various dichlorosilanes 1, trichlorosilanes 5, and tetrachlorosilane 6 to give the corresponding monochlorosilanes.

Synthesis of Functional Monosilanes by Disilane Cleavage with Phosphonium Chlorides

Santowski, Tobias,Sturm, Alexander G.,Lewis, Kenrick M.,Felder, Thorsten,Holthausen, Max C.,Auner, Norbert

supporting information, p. 3809 - 3815 (2019/02/13)

The Müller–Rochow direct process (DP) for the large-scale production of methylchlorosilanes MenSiCl4?n (n=1–3) generates a disilane residue (MenSi2Cl6?n, n=1–6, DPR) in thousands of tons annually. This report is on methylchlorodisilane cleavage reactions with use of phosphonium chlorides as the cleavage catalysts and reaction partners to preferably obtain bifunctional monosilanes MexSiHyClz (x=2, y=z=1; x,y=1, z=2; x=z=1, y=2). Product formation is controlled by the reaction temperature, the amount of phosphonium chloride employed, the choice of substituents at the phosphorus atom, and optionally by the presence of hydrogen chloride, dissolved in ethers, in the reaction mixture. Replacement of chloro by hydrido substituents at the disilane backbone strongly increases the overall efficiency of disilane cleavage, which allows nearly quantitative silane monomer formation under comparably moderate conditions. This efficient workup of the DPR thus not only increases the economic value of the DP, but also minimizes environmental pollution.
