| Chemical Properties | colourless liquid |
| Uses | Used primarily as an intermediate for silicones. |
| Uses | Dichlorodiethylsilane is used in ethchlorvynol assay. It is used in Organic Synthesis, Pharmaceuticals, Agrochemicals and Dyestuffs. |
| Production Methods | Produced by reaction of powdered silicon and ethyl chloride
at 300℃, in the presence of copper powder. |
| General Description | A colorless liquid with a pungent odor. Flash point 77°F. Corrosive to metals and tissue. Vapors are heavier than air. |
| Reactivity Profile | Chlorosilanes, such as Dichlorodiethylsilane, 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 | TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Bromoacetates and chloroacetates are extremely irritating/lachrymators. Reaction with water or moist air will release toxic, corrosive or flammable gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. |
| Fire Hazard | HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapors may travel to source of ignition and flash back. Substance will react with water (some violently) releasing flammable, toxic or corrosive gases and runoff. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water. |
| Safety Profile | Poison by
intraperitoneal route. Moderately toxic by
ingestion. Corrosive to tissue. Dangerous
fire hazard when exposed to heat, flame, or
oxidzers. Can react vigorously with
oxidizing materials. To fight fire, use foam,
Con, dry chemical. When heated to
decomposition or in reaction with water or
steam it emits toxic and corrosive fumes of
Cl-. See also CHLOROSILANES. |
