Hazard Information

Chemical Properties
Ethylene dichloride is one of the highest volume chemicals used in the United States. It is a colorless oily liquid with a chloroform-like odor, detectable over the range of 6–40 ppm,with a sweet taste. Ethylene dichloride (1,2-dichloroethane), which has a carbon-carbon single bond, should be distinguished from 1,2-dichloroethene, which has a carbon-carbon double bond. It is a skin irritant. Ethylene dichloride is also used as an extraction solvent, as a solvent for textile cleaning and metal degreasing, in certain adhesives, and as a component in fumigants for upholstery, carpets, and grain. Other miscellaneous applications include paint, varnish, and fi nish removers, soaps and scouring compounds, wetting and penetrating agents, organic synthesis, ore fl otation, and as a dispersant for nylon, rayon, styrene-butadiene rubber, and other plastics.
General Description
A clear colorless liquid with a chloroform-like odor. Flash point 56°F. Denser than water and insoluble in water. Vapors are heavier than air. Density 10.4 lb/gal.
Reactivity Profile
Liquid ammonia and ETHYLENE DICHLORIDE(107-06-2) can cause an explosion when mixed, NFPA 491M, 1991. A tank of dimethyl amino propyl amine exploded violently when ETHYLENE DICHLORIDE(107-06-2) reacted with wet ETHYLENE DICHLORIDE(107-06-2) which had been the tank's previous contents [Doyle 1973]. Halogenated aliphatic compounds, such as ETHYLENE DICHLORIDE(107-06-2), are moderately or very reactive. Reactivity generally decreases with increased degree of substitution of halogen for hydrogen atoms. Materials in this group are incompatible with strong oxidizing and reducing agents. Also, they are incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, epoxides, aluminum
Air & Water Reactions
Highly flammable. Slightly water soluble.
Hazard
Toxic by ingestion, inhalation, and skin absorption; strong irritant to eyes and skin; a carcinogen. Flammable, dangerous fire risk, explosive limits in air 6–16%. Possible carcinogen.
Health Hazard
Exposures to ethylene dichloride cause CNS depression (dizziness, drowsiness, trembling, unconsciousness), nausea, vomiting, abdominal pain, skin irritation, dermatitis, eye irritation, corneal opacity, blurred vision, headache, sore throat, cough, bronchitis, pulmonary edema (may be delayed), liver, kidney, cardiovascular system damage, cardiac arrhythmia, acute abdominal cramps, diarrhea, internal bleeding (hemorrhagic gastritis and colitis), and respiratory failure. Ethylene dichloride involves the kidneys, liver, eyes, skin, CNS, and the cardiovascular system as the target organs. Ethylene dichloride is known to cause systemic effects and has been identifi ed as a priority pollutant in many countries. Prolonged periods of inhalation of the vapors of ethylene dichloride irritate the respiratory tract. Symptoms of severe toxicity are CNS effects, liver damage, kidney damage, adrenal gland damage, cyanosis, weak and rapid pulse, and unconsciousness. Death can occur from respiratory and circulatory failure. The acute effects of ethylene dichloride are similar for all routes of entry: ingestion, inhalation, and skin absorption. Acute exposures result in nausea, vomiting, dizziness, internal bleeding, bluish-purple discoloration of the mucous membranes and skin (cyanosis), rapid but weak pulse, and unconsciousness. Acute exposures can lead to death from respiratory and circulatory failure. Autopsies in such situations have revealed widespread bleeding and damage in most internal organs. Repeated long-term exposures to ethylene dichloride have resulted in neurologic changes, loss of appetite, and other gastrointestinal problems, irritation of the mucous membranes, liver and kidney impairment, and death.
Health Hazard
Inhalation of vapors causes nausea, drunkenness, depression. Contact of liquid with eyes may produce corneal injury. Prolonged contact with skin may cause a burn.
Potential Exposure
In recent years, 1,2-dichloroethane is used in the production of vinyl chloride and as a leadscavenging agent in petrol; it has found wide use in the manufacture of ethylene glycol, diaminoethylene, polyvinyl chloride; nylon, viscose rayon; styrenebutadiene rubber, and various plastics. It is a solvent for resins, asphalt, bitumen, rubber, cellulose acetate; cellulose ester; and paint; a degreaser in the engineering, textile, and petroleum industries; and an extracting agent for soybean oil and caffeine. It is also used as an antiknock agent in gasoline; a pickling agent; a fumigant; and a dry-cleaning agent. It has found use in photography, xerography, and water softening; and also in the production of adhesives, cosmetics, pharmaceuticals, and varnishes.
First aid
Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. Keep victim warm and quiet. Effects of exposure (inhalation, ingestion or skin contact) to substance may be delayed. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. 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.with substance, immediately flush skin or eyes with running water for at least 20 minutes.

Questions And Answer

Description
1,2-Dichloroethane, also called ethylene dichloride (EDC), is a manufactured chemical that is not found naturally in the environment. It is used principally to synthesize vinyl chloride, which is further used to produce a variety of vinyl based plastics products, such as polyvinyl chloride (PVC) pipes, furniture, automobile upholstery, wall coverings, housewares, and automobile parts. It is used in solvents in closed systems for various extraction and cleaning purposes in organic synthesis. It is used as a leaded gasoline additive to remove lead, but with declining tendency. It is used as a dispersant in rubber and plastics, as a wetting and penetrating agent. It was used in ore flotation, as a metal degreaser, and in textile and PVC cleaning. It was also used as an insect fumigant for stored grains and in mushroom houses, a soil fumigant in peach and apple orchards. But due to its toxicity, it is no longer registered for use as an insect fumigant in the United States (IARC 1999).

Chemical Properties
1,2-Dichloroethane is a clear and colorless, flammable liquid which has a pleasant, chloroform-like odor, and a sweetish taste. Decomposes slowly: turns dark and acidic on contact with air, moisture, and light. The Odor Threshold is 100 ppm.It is a volatile compound. It is relatively insoluble in water (8.6 × 103 mg/l at 25 °C) but soluble in various organic solvents and is miscible with alcohol, chloroform, and ether (NLM, 2013).
Uses
1,2-dichloroethane is used in the synthesis of vinyl chloride and other organic compounds. It is also used as a solvent for nail lacquers, as a degreaser and metal cleaner, in adhesives, in pharmaceutical production, and in tobacco and spice extraction. Ethylene dichloride was historically used as an insecticide fumigant.
