Hazard Information | Back Directory | [General Description]
A clear colorless liquid with a sweet pleasant or nauseating odor. Flash point 131°F. Denser than water and insoluble in water. Toxic by inhalation and skin absorption. Used in cleaning compounds, paints, textile finishing, and as a general solvent. | [Reactivity Profile]
2,2'-DICHLORODIETHYL ETHER(111-44-4) may form phosgene or hydrogen when heated to high temperature. Oxidizes readily in air to form unstable peroxides that may explode spontaneously [Bretherick, 1979 p.151-154]. Mixing in equal molar portions with the following substances in a closed container caused the temperature and pressure to increase: chlorosulfonic acid and oleum [NFPA 1991]. | [Air & Water Reactions]
Flammable. Insoluble in water. Reacts slowly with water to form HCl. Oxidizes readily in air to form unstable peroxides that may explode spontaneously [Bretherick, 1979 p.151-154]. | [Health Hazard]
This material is very toxic; the probable oral lethal dose is 50-500 mg/kg, or between 1 teaspoonful and 1 ounce for a 150 pound person. It can be a central nervous system depressant in high concentrations. It is extremely irritating to the eyes, nose, and respiratory passages. It can penetrate the skin to cause serious and even fatal poisoning. Poisonous; may be fatal if inhaled, swallowed or absorbed through skin. | [Potential Exposure]
Dichloroethyl ether is used as a soil
fumigant, an insecticide, and an acaricide; in the manufacture of paint, varnish, lacquer, soap, and finish removers. It
is also used as a solvent for cellulose esters, naphthalenes,
oils, fats, waxes, greases, pectin, tar, and gum; in dry cleaning and in textile scouring. | [Fire Hazard]
May form phosgene or hydrogen chloride in fires. There is danger of explosion when ethers are heated or exposed to flames or sparks. Ethers tend to form peroxides; when ethers containing peroxides are heated, they can detonate. May be ignited by heat, sparks, or flames. Container may explode in heat of fire. Vapor explosion and poison hazard indoors, outdoors or in sewers. Decomposes in the presence of moisture to form hydrochloric acid. Emits toxic fumes when heated to decomposition. Reacts vigorously with oleum and chlorosulfonic acid. Ethers tend to form peroxides upon standing. Heating peroxide-containing ethers can cause detonation. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if
heart action has stopped. Transfer promptly to a medical
facility. When this chemical has been swallowed, get
medical attention. Give large quantities of water and induce
vomiting. Do not make an unconscious person vomit.
Medical observation is recommended for 24 to 48 hours
after breathing overexposure, as pulmonary edema may be
delayed. As first aid for pulmonary edema, a doctor or
authorized paramedic may consider administering a drug or
other inhalation therapy | [Shipping]

Bis(2-chloroethyl) ether does not occur naturally in the environment. In Canada, this
compound enters the environment as a by-product from chlorination of waste streams containing
ethylene, propylene (Environment Canada, 1993) or ethyl ether (quoted, Verschueren, 1983). | [Environmental Fate]
Biological. When 5 and 10 mg/L of bis(2-chloroethyl)ether were statically incubated
in the dark at 25°C with yeast extract and settled domestic wastewater inoculum, complete
degradation was observed after 7 days (Tabak et al., 1981). Chemical/Physical. Bis(2-chloroethyl)ether is subject to hydrolysis (Enfield and Yates,
1990; NIOSH, 1994). The hydrolysis rate constant for bis(2-chloroethyl)ether at pH 7 and
25°C was determined to be 2.6 × 10–5/hour, resulting in a half-life o Emits chlorinated acids when incinerated (Sittig, 1985). | [storage]
Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with BCEEyou should be trained on its proper handling and storage.Before entering confined space where this chemical may bepresent, check to make sure that an explosive concentrationdoes not exist. Bis (2-chloroethyl) ether must be stored toavoid contact with strong oxidizers, such as chlorine, bromine, and chlorine dioxide, since violent reactions occur,and moisture. Store in tightly closed containers in a cool,dry, well-ventilated area away from heat. Sources of ignition, such as smoking and open flames are prohibited wherebis (2-chloroethyl) ether is used, handled, or stored in amanner that could create a potential fire or explosion hazard. A regulated, marked area should be established wherethis chemical is handled, used, or stored in compliance withOSHA Standard 1910.1045. | [Purification Methods]
Wash the ether with conc H2SO4, then Na2CO3 solution, dry with anhydrous Na2CO3, and finally pass it through a 50cm column of activated alumina before distillation. Altern |
