1,2-디클로로에탄 C화학적 특성, 용도, 생산


물에 약간 녹으며 에탄올·에테르에 잘 녹는다.


1,2-다이클로로에테인(1,2-dichloroethane)은 화학물질의 하나로 염화에틸렌라고도 하며, 이염화 에틸렌(ethylene dichloride, EDC)이라는 이름으로도 알려져있다. 이 물질은 주로 PVC 생산을 위한 주요 물질인 폴리염화 단량체(vinyl chloride monomer, VCM, chloroethene)를 제조하는 데 주로 사용된다. 또한 유기화합물을 합성하는 데 중간체나 용매로도 많이 사용된다.


염화철(III)을 촉매로 하고 액체상 또는 기체상으로 에틸렌과 염소를 반응 시켜 공업적으로 제조한다.

화학적 성질

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.

화학적 성질

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.

물리적 성질

Clear, colorless, oily liquid with a pleasant, chloroform-like odor. The average least detectable odor threshold concentrations in water at 60 °C and in air at 40 °C were 12 and 52 mg/L, respectively (Alexander et al., 1982). Experimentally determined detection and recognition odor threshold concentrations were 25 mg/m3 (6 ppmv) and 165 mg/m3 (41 ppmv), respectively (Hellman and Small, 1974).


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.


1,2-Dichloroethane is used in the manufacture 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.

반응 프로필

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

1,2-Dichloroethane is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.


Improper use of insecticidal fumigant formulation containing 1,2-dichloropropane and carbon tetrachloride (Granosan).


Biological. Methanococcus thermolithotrophicus, Methanococcus deltae, and Methanobacterium thermoautotrophicum metabolized 1,2-dichloroethane releasing methane and ethylene (Belay and Daniels, 1987). 1,2-Dichloroethane showed slow to moderate biodegradative activity with concomitant rate of volatilization in a static-culture flask-screening test (settled domestic wastewater inoculum) conducted at 25 °C. At concentrations of 5 and 10 mg/L, percent losses after 4 wk of incubation were 63 and 53, respectively. At a substrate concentration of 5 mg/L, 27% was lost due to volatilization after 10 d (Tabak et al., 1981).
Photolytic. Titanium dioxide suspended in an aqueous solution and irradiated with UV light (λ = 365 nm) converted 1,2-dichloroethane to carbon dioxide at a significant rate (Matthews, 1986).
The rate constant for the reaction of 1,2-dichloroethane and OH radicals in the atmosphere at 300 K is 1.3 x 10-11 cm3/molecule?sec (Hendry and Kenley, 1979). At 296 K, a photooxidation rate constant of 2.2 x 10-13 cm3/molecule?sec was reported for the reaction with OH radicals resulting in a half-life of 1.7 months (Howard and Evenson, 1976).
Chemical/Physical. Anticipated products from the reaction of 1,2-dichloroethane with ozone or OH radicals in the atmosphere are chloroacetaldehyde, chloroacetyl chloride, formaldehyde, and ClHCHO (Cupitt, 1980).

신진 대사 경로

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.


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.

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.]


Ethylene dichloride (1) had been detected in surface and ground water as an environmental contaminant, resulting from both industrial and agricultural uses. It is also detected following the chlorination of drinking water. Ethylene dichloride is stable to hydrolytic degradation at environmentally relevant pH and temperature.
The primary dissipation mechanism of ethylene dichloride is volatilisation (DT50 30 min, Moore et al., 1991). Ethylene dichloride interacts with hydroxyl radicals produced by photo-oxidation in air to yield chloracetyl chloride (2, Howard and Evenson, 1976; Radding et al., 1977). The DT50 of ethylene dichloride in the vapour phase under atmospheric photo-oxidation conditions was 12-122 days (Atkinson, 1985).

비 호환성

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.

폐기물 처리

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
