사메틸 실란 C화학적 특성, 용도, 생산
화학적 성질
Colorless clear liquid용도
NMR reference standard. In semiconductor applications (chemical vapor deposition). Tetramethylsilane (TMS) is used as a chemical shift reference for proton, carbon-13, and silicon-29 analysis in organic solvents and is given 0 as its chemical shift position.정의
ChEBI: Tetramethylsilane is an organosilicon compound that is silane in which the hydrogens have been replaced by methyl groups.일반 설명
Tetramethylsilane appears as a colorless, mildly acidic volatile liquid. A serious fire hazard. Mildly toxic by ingestion. Emits acrid smoke and fumes when heated to high temperatures. Less dense than water and insoluble in water, but soluble in most organic solvents. Used as an aviation fuel and as an internal standard for nmr analytical instruments.공기와 물의 반응
Highly flammable. Tetramethylsilane is insoluble in water.반응 프로필
Hydrides, such as Tetramethylsilane, are reducing agents and react rapidly and dangerously with oxygen and with other oxidizing agents, even weak ones. Thus, they are likely to ignite on contact with alcohols. Hydrides are incompatible with acids, alcohols, amines, and aldehydes.위험도
Flammable, high fire risk.건강위험
May cause toxic effects if inhaled or absorbed through skin. Inhalation or contact with material may irritate or burn skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.화재위험
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.Purification Methods
Distil it from conc H2SO4 (after shaking with it) or LiAlH4, through a 5ft vacuum-jacketed column packed with glass helices into an ice-cooled condenser, then percolate it through silica gel to remove traces of halide. [Beilstein 4 IV 3875.]사메틸 실란 준비 용품 및 원자재
