Chemische Eigenschaften
Colorless clear liquid
Verwenden
Chlorodimethylsilane is used to prepare vinyldimethylsilanols for palladium-catalyzed cross-coupling with aryl iodides. Chlorodimethylsilane in combination with a tertiary amine such as triethylamine is another useful reagent for the synthesis of hydrodimethylsilyl ethers, especially for large scale preparations.
Application
The popular uses of chlorodimethylsilane are listed as below:
Will form high-boiling polymeric by-products with aqueous work-up.
A monomer ('building block') in the production of silicone polymers. Silicone polymers may be oils, greases, rubbers and resins and have a wide-range of uses.
In the electronics industry for the production of ultra-pure polysilicon and in the manufacture of semiconductors and photovoltaics.
Although the end uses of products made from chlorodimethylsilane will vary, it can be assumed that due to its highly reactive nature, no residual unreacted material will be present in any of the final products.
Allgemeine Beschreibung
A colorless fuming liquid with a pungent, burning odor. Flash point -18°F. Boiling point 95°F. Density about 6.9 lb / gal. Extremely corrosive to skin and respiratory tissues, both as a liquid and vapor. Vapors are heavier than air.
Air & Water Reaktionen
Highly flammable. Reacts violently on contact with water to liberate heat and hydrogen chloride gas.
Reaktivität anzeigen
Chlorosilanes, such as DIMETHYLCHLOROSILANE, 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.
Health Hazard
May cause toxic effects if inhaled or ingested/swallowed. Contact with substance may cause severe burns to 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.
Brandgefahr
Flammable/combustible material. May be 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.
Flammability and Explosibility
Extremely flammable

The initial threshold screening levels (ITSLs) for chlorodimethylsilane (CDMS) are 5400 μg/m3 (1-hr averaging time) and 52 μg/m3 (annual averaging time).
