Bromoethane Usage And Synthesis
Chemical Propertiescolourless liquid with an ether-like odour
Chemical PropertiesEthyl bromide is a colorless liquid (turns yellow on contact with air) with an ethereal odor and a burning taste. A gas above the boiling point.
Physical propertiesClear, colorless to yellow, volatile liquid with an ether-like odor. Odor threshold concentration is 3.1 ppm (quoted, Amoore and Hautala, 1983).
UsesEthylating agent in organic synthesis; as refrigerant. Formerly used as a topical and inhalation anesthetic.
UsesEthyl bromide is used as a refrigerant and asan ethylating agent. It was formerly used asa topical anesthetic.
DefinitionA colorless volatile compound, used as a refrigerant. It can be made from ethene and hydrogen bromide.
General DescriptionA colorless volatile liquid. Slightly soluble in water and denser than water. Flash point below 0°F. Vapors are heavier than air. Toxic by inhalation. Irritates skin and eyes. Used to make pharmaceuticals and as a solvent.
Air & Water ReactionsHighly flammable. Slightly soluble in water and denser than water. Turns yellow on exposure to air and light.
Reactivity ProfileBromoethane will react with steam to produce toxic and corrosive fumes. Bromoethane can react vigorously with oxidizers. Bromoethane reacts with strong bases. Bromoethane also reacts with chemically active metals such as sodium, potassium, calcium, powdered aluminum, zinc and magnesium. Bromoethane will attack some forms of plastics, rubber and coatings.
HazardToxic by ingestion, inhalation, and skin absorption; strong irritant. Questionable carcinogen. Flammable, dangerous fire hazard, explosion limits in air 6–11%.
Health HazardTOXIC; may be fatal if inhaled, ingested or absorbed through skin. Inhalation or contact with some of these materials will 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.
Health HazardEthyl bromide is a depressant of the centralnervous system, causing narcosis. The healthhazard is greater than with ethyl chloride.In addition to the narcotic effects that occurat exposure to high concentrations, othertoxic symptoms include irritation of the eyesand respiratory tract, pulmonary edema, fattydegeneration of the liver and renal tissue, anddamage to the liver, kidney, and intestine. A15-minute exposure to a 15% concentrationof vapor in air was lethal to rats. The oralLD50 value in rats is 1350 mg (NIOSH 1986).
Fire HazardHIGHLY 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 and poison 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.
Safety ProfileConfirmed carcinogen. Moderately toxic by ingestion and intraperitoneal routes. Mddly toxic by inhalation. An eye and skin irritant. Physiologically, it is an anesthetic and narcotic. Its vapors are markedly irritating to the lungs on inhalation for even short periods. It can produce acute congestion and edema. Liver and ludney damage in humans has been reported. It is much less toxic than methyl bromide, but more toxic than ethyl chloride. It is a preparative hazard. Dangerously flammable by heat, open flame (sparks), oxidizers. Moderately explosive when exposed to flame. Reacts with water or steam to produce toxic and corrosive fumes. Vigorous reaction with oxidizing materials. To fight fire, use CO2, dry chemical. Ready decomposes when heated to emit toxic fumes of Br-. See also BROMIDES.
Potential ExposureThis chemical is used as an industrial chemical, pharmaceutical, and veterinary drug; as an ethylating agent in organic synthesis and gasoline; as a refrigerant; and as an extraction solvent. It has limited use as a local anesthetic
Environmental fateBiological. A strain of Acinetobacter sp. isolated from activated sludge degraded ethyl bromide to ethanol and bromide ions (Janssen et al., 1987). When Methanococcus thermolithotrophicus, Methanococcus deltae, and Methanobacterium thermoautotrophicum were grown with H2-CO2 in the presence of ethyl bromide, methane and ethane were produced (Belay and Daniels, 1987).
Groundwater. Groundwater under reducing conditions in the presence of hydrogen sulfide converted ethyl bromide to sulfur-containing products (Schwarzenbach et al., 1985).
Chemical/Physical. Hydrolyzes in water forming ethanol and bromide ions. The estimated hydrolysis half-life at 25 °C and pH 7 is 30 d (Mabey and Mill, 1978).
ShippingUN1891 Ethyl bromide, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
Purification MethodsThe main impurities are usually EtOH and water, both of which form azeotropes with it. Ethanol and unsaturated compounds can be removed by washing with conc H2SO4 until no further coloration is produced. The ethyl bromide is then washed with water, aqueous Na2CO3, and water again, then dried with CaCl2, MgSO4 or CaH2, and distilled from P2O5. Olefinic impurities can also be removed by storing the ethyl bromide in daylight with elemental bromine, later removing the free bromine by extraction with dilute aqueous Na2SO3, drying the ethyl bromide with CaCl2 and fractionally distilling it. Alternatively, unsaturated compounds can be removed by bubbling oxygen containing ca 5% ozone through the liquid for an hour, then washing with aqueous Na2SO3 to hydrolyse ozonides and remove hydrolysis products, followed by drying and distillation. [Beilstein 1 IV 150.]
IncompatibilitiesMay form explosive mixture with air. Hydrolyzes in water, forming hydrogen bromide (HBr). Oxidizers may cause fire or explosions. Fire and explosions may be caused by contact with chemically active metals: aluminum, magnesium or zinc powders; lithium, potassium, sodium. Attacks some plastic, rubber and coatings. Note: Chlorinating agents destroy nitrogen mustards. Dry chlorinated lime and chloramines with a high content of active chlorine, vigorously chlorinate nitrogen mustards to the carbon chain, giving low toxicity products. In the presence of water this interaction proceeds less actively. They are rapidly oxidized by peracids in aqueous solution at weakly alkaline pH. In acid solution the oxidation is much slower
Waste DisposalControlled incineration with adequate scrubbing and ash disposal facilities.
