| | Ethyldichlorosilane Usage And Synthesis |
| Chemical Properties | Colorless liquid.Readily
hydrolyzed by moisture, with the liberation of
hydrogen and hydrogen chloride. | | Chemical Properties | Ethyl dichlorosilane is a colorless liquid.
Sharp, irritating odor | | Uses | Intermediate for silicones. | | Application | Will form high-boiling polymeric by-products with aqueous
work-up. | | General Description | A colorless fuming liquid with a pungent odor. Flash point 30°F. Vapor and liquid may cause burns. Denser than water. Vapors heavier than air. | | Air & Water Reactions | Highly flammable. Based on the properties of similar materials, there is the possibility that the reaction of Ethyldichlorosilane with water may be vigorous or violent. Products of the reaction include hydrogen chloride. The reaction generates heat and this heat may be sufficient to ignite the product. The chlorosilicon hydrides(ClxSiHy) are spontaneously flammable in air [NFPA 1991]. | | Reactivity Profile | Chlorosilanes, such as Ethyldichlorosilane, 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. | | Hazard | Flammable, dangerous fire risk. Strong irritant to eyes and skin. | | Health Hazard | Inhalation irritates mucous membranes. Contact with liquid causes severe burns of eyes and skin. Ingestion causes severe burns of mouth and stomach. | | Chemical Reactivity | Reactivity with Water Reacts vigorously, evolving hydrogen chloride (hydrochloric acid); Reactivity with Common Materials: Reaction with surface moisture will generate hydrogen chloride, which corrodes common metals; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Flood with water, rinse with sodium bicarbonate or lime solution; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent. | | Safety Profile | Poison by ingestion and
inhalation. A severe irritant to skin, eyes,
and mucous membranes. Corrosive.
Dangerous fire hazard if exposed to heat,
open flames, or powerful oxidizers. Will
react with water or steam to produce heat
and toxic and corrosive fumes. To fight fire,
use foam, dry chemical, mist, spray. When
heated to decomposition it emits toxic
fumes of Cland phosgene. See also
CHLOROSILANES. | | Potential Exposure | This material is used in silicone polymer manufacture. | | Shipping | UN1183 Ethyldichlorosilane, Hazard Class: 4.3;
Labels: 4.3-Dangerous when wet material; 8-Corrosive
material | | Incompatibilities | Incompatible with oxidizers (chlorates,
nitrates, peroxides, permanganates, perchlorates, chlorine,
bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases,
strong acids, oxoacids, and epoxides. Chlorosilanes react
vigorously with bases and both organic and inorganic acids
generating toxic and/or flammable gases. Chlorosilanes
react with water, moist air, or steam to produce heat and
toxic, corrosive fumes of hydrogen chloride. They may also
produce flammable gaseous hydrogen. Attacks metals in
