| 輸送ラベル（DOT） | Flammable Liquid Corrosive |
| 火災危険 | 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. (EPA, 1998)· HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.Highly flammable. Gives off irritating or toxic fumes (or gases) in a fire. Vapour/air mixtures are explosive. |
| 火災の可能性 | ... Silanes ... form spontaneously flammable ... mixtures with air. /Silanes/... Trichlorosilane is highly flammable. /Trichlorosilane/ |
| 健康有害性 | 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. (EPA, 1998) |
用途
用途
シリコン樹脂、シリコーン撥水剤、シリコーン繊維処理剤等のコモノマー。種々のケイ素化合物の合成原料。
使用
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.
一般的な説明
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.
製法・合成法
調製方法
Produced by Grignard reaction of silicon tetrachloride and methylmagnesium chloride.

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.
