Methyltrichlorosilane

메틸트리클로로실란 C화학적 특성, 용도, 생산

화학적 성질

Colorless clear liquid

물리적 성질

bp 66 °C; d 1.273 g cm?3.

용도

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.

생산 방법

Produced by Grignard reaction of silicon tetrachloride and methylmagnesium chloride.

일반 설명

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.

반응 프로필

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.

위험도

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

건강위험

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.

화재위험

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.
