106-93-4 - Application:

1,2-Dibromoethane (EDB) (CAS: 106-93-4) is a volatile colorless liquid with special sweet taste at normal temperature and pressure. Used as an intermediate in organic synthesis, also used as solvent, scavenger for lead in gasoline, grain fumigant and in the manufacture of other chemicals.

Used as an ethylation reagent and solvent; Used as a nematicide and a synthetic plant growth regulator in agriculture; Used as an intermediate for synthesizing diethylbromophenylacetonitrile in medicine; Used as a flame retardant for bromoethylene and vinylidene dibromobenzene; Also used as gasoline anti-shock liquid lead elimination agent, metal surface treatment agent and fire extinguishing agent. Motor gasoline uses a mixture of dibromoethane and dichloroethane to reduce cost, while aviation gasoline uses pure dibromoethane.

1,2-Dibromoethane (EDB) is used as a fumigant for grains. Most of the uses of 1,2-Dibromoethane have been stopped in the United States; however, it is still used as a fumigant for treatment of logs for termites and beetles, for the control of moths and beehives, and as a preparation for dyes and waxes.

106-93-4 - Uses:

Historically, the primary use of 1,2-dibromoethane has been as a lead scavenger in antiknock mixtures added to gasolines (IPCS 1996). Lead scavenging agents transform the combustion products of tetraalkyl lead additives to forms that are more likely to be vaporized from engine surfaces. In 1978, 90% of the 1,2-dibromoethane produced was used for this purpose (ATSDR 1992). Annual consumption of 1,2-dibromoethane in the United States has decreased since the U.S. Environmental Protection Agency banned the use of lead in gasoline.

106-93-4 - Reactivity Profile:

1,2-Dibromoethane slowly decomposes in the presence of light and heat. Turns brown upon exposure to light. Corrosive to iron and other metals. May decompose upon contact with alkalis. Incompatible with oxidizing agents. Reacts with sodium, potassium, calcium, powdered aluminum, zinc, magnesium and liquid ammonia. May attack some plastics, rubber and coatings. May poison platinum catalysts [Hawley]. Reacts as an alkylating agent.

106-93-4 - Hazard:

Probable carcinogen. Toxic by inhalation, ingestion, and skin absorption; strong irritant to eyes and skin.

106-93-4 - Health Hazard:

1,2-Dibromoethane is toxic by inhalation,ingestion, or skin contact. The acute toxicsymptoms are depression of the central ner vous system, irritation and congestion oflungs, hepatitis, and renal damage. Chronicexposure can produce conjunctivitis, bron chial irritation, headache, depression, lossof appetite, and loss of weight. Recoveryoccurs after cessation of exposure. Prolongedor repeated exposures to high concentrationscan be fatal to animals and humans. Lethalconcentration for a 2-hour exposure period is400 ppm in rats.

1,2-Dibromoethane is moderate to highlytoxic by ingestion. Its toxicity is far greaterthan that of 1,2-dichloroethane. An oralintake of 5 to 10 mL of the liquid can be fatalto humans. Death occurs from necrosis of theliver and kidney damage. The oral LD50 val ues varied between 50 and 125 mg/kg fordifferent species of laboratory animals. Vapors are irritant to the eyes. Contactwith the liquid can damage vision. Skincontact may produce severe irritation andblistering. Mutagenic tests were positive, while thehistidine reversion–Ames test gave incon clusive results (NIOSH 1986). 1,2-Dibromo ethane is carcinogenic to animals and issuspected to cause cancer in humans. Inhala tion of this compound produced tumors inthe lungs and nose in mice and rats. Oraladministration caused cancers in the liver andgastrointestinal tract.

106-93-4 - Agricultural Uses:

Fumigant, Nematicide: Not approved for use in EU countries. Not registered for use in the U.S. Persons whose clothing or skin is contaminated with liquid ethylene dibromide (above 10℃) can secondarily contaminate others by direct contact or through off-gassing vapor. Ethylene dibromide was used extensively as a pesticide and an ingredient of soil, vegetable, fruit, and grain fumigant formulations. Still used in India, South Africa and other countries.

106-93-4 - Safety Profile:

Confirmed carcinogen with experimental carcinogenic, neoplastigenic, and teratogenic data. Human poison by ingestion. Experimental poison by ingestion, sktn contact, intraperitoneal, and possibly other routes. Moderately toxic by inhalation and rectal routes. Human systemic effects by ingestion: hypermothty, barrhea, nausea or vomiting, decreased urine volume or anuria. Experimental reproductive effects. Human mutation data reported. A severe skin and eye irritant. Implicated in worker sterdity. When heated to decomposition it emits toxic fumes of Br-. See also ETHYLENE DICHLORIDE and BROMIDES.

106-93-4 - Handle:

Work with EDB should be conducted in a fume hood to prevent exposure by inhalation, and appropriate impermeable gloves and safety goggles should be worn to prevent skin contact. Gloves and protective clothing should be changed immediately if EDB contamination occurs. Since EDB can penetrate neoprene and other plastics, protective apparel made of these materials does not provide adequate protection from contact with EDB.

106-93-4 - Shipping:

UN1605/154 Ethylene dibromide, Hazard Class: 6.1; Labels: 6.1-Poison Inhalation Hazard, Inhalation Hazard Zone B

106-93-4 - Incompatibilities:

Reacts vigorously with chemically active metals; liquid ammonia, strong bases; strong oxidizers; causing fire and explosion hazard. Light, heat, and moisture can cause slow decomposition, forming hydrogen bromide. Attacks fats, rubber, some plastics and coatings.
