Tetramethylsilane Chemical Properties,Uses,Production

Chemical Properties

Colorless clear liquid

Definition

ChEBI: An organosilicon compound that is silane in which the hydrogens have been replaced by methyl groups.

Uses

NMR reference standard. In semiconductor applications (chemical vapor deposition).

General Description

A colorless, mildly acidic volatile liquid. Flash point 0°F. Boiling point 78°F. 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.

Air & Water Reactions

Highly flammable. Tetramethylsilane is insoluble in water.

Reactivity Profile

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.

Hazard

Flammable, high fire risk.

Health Hazard

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.

Fire Hazard

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.]
