1,2-Dichloroethane Chemical Properties,Uses,Production

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

Ethylene dichloride (1,2-dichloroethane) is a colourless oily liquid with a chloroform-like odour, 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.

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.

Chemical Properties

1,2-Dichloroethane is a 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.

Uses

1,2-Dichloroethane is used in the manufac ture of acetyl cellulose and vinyl chloride; inpaint removers; as a fumigant; as a degreaser;as a wetting agent; and as a solvent for oils,waxes, gums, resins, and rubber.

Uses

Ethylene dichloride (1,2-dichloroethane), otherwise known as EDC, is produced by reacting chlorine or anhydrous hydrochloric acid with ethylene. The largest single use for EDC is the production of vinyl chloride monomer, which is used to produce poly vinyl chloride (PVC). EDC can also be used in the manufacture of other organic compounds, and as a solvent. Ethylene dichloride is a colorless, oily liquid with a chloroform-like smell. It has many uses in industry, with principal ones being the following:
As an intermediate in the manufacture of methyl chloroform, perchloroethylene, ethylene amines, polyvinyl chloride (PVC), sulfide compounds, vinyl chloride, and trichloroethane.
As an additive in gasoline (used as a lead scavenger), pharmaceutical products, color film, and pesticides.
As a solvent for rubber, tobacco extract, paint, printing inks, and varnish.
Miscellaneous uses include as an ingredient in fingernail polish, for metal degreasing, in extracting spices, and as a dry cleaning agent.
Two of the major uses for this chemical are the manufacture of PVC and as a lead scavenger in gasoline. The process for making EDC begins with crude oil or natural gas and sodium chloride. The hydrocarbon raw materials are converted to ethene (ethylene), and sodium chloride is electrolyzed to pruduce chlorine.
2 NaCl + 2 H2O = Cl2 + 2 NaOH + H2
This electrochemical process is also the major industrial route for sodium hydroxide production, so essentially the only side product from this initial reaction is hydrogen gas, which is later converted to water. Once the ethylene is produced from the crude hydrocarbons, it is reacted with chlorine gas:
C2H4 + Cl2 - C2H4Cl (1,2-dichloroethane)
Although its common name would lead one to believe otherwise, EDC does not contain a double bond. In one of its major industrial processes, the manufacture of PVC, the following reaction is carried out:
C2H4Cl = C2H3Cl (vinyl chloride) + HC1
The HC1 produced in this reaction is recycled to be used in the first reaction by oxidation of the hydrogen-chlorine bond.
EDC is a carcinogen and a mutagen. Assessments of 1,2-dichloroethane are in progress under the authority of the Clean Air Act, Safe Drinking Water Act (SDWA), Toxic Substances Control Act (TSCA), and the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). EDC is also listed under CERCLA as a hazardous material, and is required to be reported as such under Title III of SARA, otherwise known as the Community Right-to-Know Act.

Air & Water Reactions

Highly flammable. Slightly water soluble.

Reactivity Profile

Liquid ammonia and 1,2-Dichloroethane can cause an explosion when mixed, NFPA 491M, 1991. A tank of dimethyl amino propyl amine exploded violently when 1,2-Dichloroethane reacted with wet 1,2-Dichloroethane which had been the tank's previous contents [Doyle 1973]. Halogenated aliphatic compounds, such as 1,2-Dichloroethane , 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

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.

Health Hazard

The toxic symptoms from exposure to 1,2-dichloroethane include depression of the cen tral nervous system, irritation of the eyes,corneal opacity, nausea, vomiting, diarrhea,ulceration, somnolence, cyanosis, pulmonaryedema, and coma. Repeated exposure mayproduce injury to the kidney and liver. Inges tion of the liquid can cause death. A fataldose in humans may range between 30 and50 mL. The liquid is an irritant to the skinand damaging to the eyes.

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.

As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.

Metabolic pathway

Resting cell suspensions of the soil methylotroph Methylosinus trichosporium OB-3b rapidly dehalogenate 1,2-dichloroethane, resulting in the formation of chloroethanol via direct hydroxylation of one of the C-Cl bonds, and this ethanol is rapidly oxidized to yield chloroacetic acid.

storage

Ethylene dichloride should be kept protected against physical damage. Store in a cool, dry, well-ventilated location, away from any area where the fi re hazard may be acute. Outside or detached storage is preferred. Separate from incompatibles. Containers should be bonded and grounded for transfer to avoid static sparks.

Shipping

UN1184 Ethylene dichloride, Hazard Class: 3; Labels: 3-Flammable liquid, 6.1-Poisonous materials. Note: United States DOT 49CFR172.101, Inhalation Hazardous Chemical as 1,2-Dichloroethane

Purification Methods

It is usually prepared by chlorinating ethylene, so that likely impurities include higher chloro derivatives and other chloro compounds depending on the impurities originally present in the ethylene. It forms azeotropes with water, MeOH, EtOH, trichloroethylene, CCl4 and isopropanol. Its azeotrope with water (containing 8.9% water, and b 77o) can be used to remove gross amounts of water prior to final drying. As a preliminary purification step, it can be steam distilled, and the lower layer is treated as below. Shake it with conc H2SO4 (to remove alcohol added as an oxidation inhibitor), wash with water, then dilute KOH or aqueous Na2CO3 and again with water. After an initial drying with CaCl2, MgSO4 or by distillation, it is refluxed with P2O5, CaSO4 or CaH2 and fractionally distilled. Carbonyl-containing impurities can be removed as described for chloroform. [Beilstein 1 IV 131.]

Incompatibilities

May form explosive mixture with air. Reacts violently with strong oxidizers and caustics; chemically active metals, such as magnesium or aluminum powder, sodium and potassium; alkali metals; alkali amides; liquid ammonia. Decomposes to vinyl chloride and HCl above 600℃. Attacks plastics, rubber, coatings. Attacks many metals in presence of water.

Waste Disposal

Incineration, preferably after mixing with another combustible fuel. Care must be exercised to assure complete combustion to prevent the formation of phosgene. An acid scrubber is necessary to remove the halo acids produced

Precautions

Occupational workers should avoid use of ethylene dichloride along with oxidizing agents, strong alkalis, strong caustics, magnesium, sodium, potassium, active amines, ammonia List of Chemical Substances
