Chemische Eigenschaften

white crystalline powder

Chemische Eigenschaften

Hexachloroethane is a white solid with a camphor-like odor. It gradually evaporates when it is exposed to air.

Physikalische Eigenschaften

Rhombic, triclinic or cubic, colorless crystals with a camphor-like odor. Odor threshold concentration is 0.15 ppm (quoted, Amoore and Hautala, 1983).

Verwenden

Hexachloroethane is used as a solvent, infireworks and smoke devices; in explosives,in celluloid, as an insecticide, and as a rubbervulcanizing accelerator. Earlier it was used asan anthelmintic for livestock.

Verwenden

The applications of hexachloroethane have been extensive; however, industrial uses are diminishing. Hexachloroethane is used primarily in military smoke munitions (e.g., smoke pots, grenades, cartridges, and projectiles used to generate “smoke” or “fog”) and in pyrotechnics.
The estimated average annual use of hexachloroethane from 1966 to 1977 at a major facility manufacturing smoke and pyrotechnic devices was 192,802 lb. In the 1970s, about half of the hexachloroethane distributed was used to manufacture military smoke-producing and pyrotechnic devices, 30% to 40% to manufacture degassing pellets to remove air bubbles from molten ore at aluminum foundries, and 10% to 20% as an antihelminthic to control liver flukes in sheep and cattle. The U.S. Food and Drug Administration withdrew approval for the use of hexachloroethane as an antihelminthic in 1971, and it probably is no longer used for this purpose (ATSDR 1997). Its use for degassing aluminum also has been almost completely phased out in the United States (EPA 1999). Other uses in metallurgy include refining alloys, removing impurities from molten metals, recovering metals from ores or smelting products, and as a degassing agent for magnesium; however, the European Union began phasing out the use of hexachloroethane in nonferrous metals in 1998 (EC 1998).
A number of other past uses of hexachloroethane have been identified, but many of these likely have been discontinued or involve the use of only limited quantities. Hexachloroethane is used as a laboratory chemical and as an ingredient in various fungicidal and insecticidal formulations, extreme-pressure lubricants, and plastics (ATSDR 1997, IARC 1999, HSDB 2009). Other past uses include as a moth repellent and in the chemical industry as a polymer additive, a plasticizer for cellulose esters, an accelerator, a vulcanizing agent, a process solvent in rubber manufacturing, a retardant in fermentation processes, and a component of submarine paints, and in the production of some types of synthetic diamonds. It has also been used as a component of fire-extinguishing fluids, an additive in combustible liquids (ignition suppressant), and an inhibitor of the explosiveness of methane and the combustion of ammonium perchlorate (IARC 1979, 1999, HSDB 2009).

Verwenden

In metallurgy for refining aluminum alloys, removing impurities from molten metals, recovering metal from ores or smelting products. Degassing agent for magnesium; to inhibit explosiveness of methane and combustion of ammonium perchlorate. Smoke generator in grenades; in pyrotechnics. Ignition suppressant, in fire extinguishing fluids, polymer additive, flame-proofing agent, vulcanizing agent. In production of synthetic diamonds.

Definition

ChEBI: A member of the class of chloroethanes that is ethane in which all the hydrogens are replaced by chloro groups.

Allgemeine Beschreibung

Hexachloroethane is a colorless, crystalline solid with a camphor-like odor. Hexachloroethane may cause illness from inhalation or ingestion and may irritate skin, eyes and mucous membranes. When heated to high temperatures Hexachloroethane may emit toxic fumes. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Hexachloroethane is used to make other chemicals.

Air & Water Reaktionen

Insoluble in water.

Reaktivität anzeigen

Hexachloroethane can react with hot iron, zinc and aluminum. Dehalogenation of Hexachloroethane by reaction with alkalis and metals will produce unstable chloroacetylenes. Hexachloroethane can also react with strong oxidizing agents. .

Hazard

Toxic by ingestion and inhalation, strong irritant, absorbed by skin. Possible carcinogen.

Health Hazard

Compound is a powerful narcotic and liver poison; may also cause changes in blood composition and neurological disturbances. Repeated exposure by inhalation can be fatal. Ingestion causes vomiting, diarrhea, severe mucosal injury, liver necrosis, cyanosis, unconsciousness, loss of reflexes, and death. Contact with eyes causes irritation and lachrymation. Can be absorbed through the skin and may produce severe skin lesions.

Health Hazard

Vapors of hexachloroethane are an irritant tothe eyes and mucous membranes. Oral dosesof 1000 mg/kg produced weakness, stagger ing gait, and twitching muscles in dogs.Rabbits fed 1000 mg/kg for 12 days devel oped necrosis; a lower amount, 320 mg/kg,caused liver degeneration; no effects wereobserved at a dose level of 100 mg/kg(Weeks 1979).
Acute inhalation toxicity is of a loworder in animals. Subacute toxic effectsin dogs exposed to 260-ppm vapors ofhexachloroethane for 6 hours per day, 5days a week for 6 weeks were tremors,ataxia, hypersalivation, head bobbling, andfacial muscular fasciculations (Weeks 1979).The lethal concentration in rats is 5900 ppmfrom an 8-hour exposure.
LD50 value, oral (rats): 4460 mg/kg
Tests for mutagenicity and teratogenic ity were negative. The carcinogenic poten tial of hexachloroethane was noted in testanimals only at extremely heavy dosagesgiven continuously for a long period of time(ACGIH 1986). It caused liver tumors inmice.

Brandgefahr

Special Hazards of Combustion Products: Irritating hydrogen chloride vapor may form in fire.

mögliche Exposition

In the US, about half the HCE is used by the military for smoke-producing devices. It is also used to remove air bubbles in melted aluminum. It may be present as an ingredient in some fungicides, insecticides, lubricants, and plastics. It is no longer made in the United States, but it is formed as a by-product in the production of some chemicals. Can be formed by incinerators when mate rials containing chlorinated hydrocarbons are burned. Some HCE can also be formed when chlorine reacts with carbon compounds in drinking water. As a medicinal, HCE is used as an anthelmintic to treat fascioliasis in sheep and cattle. It is also added to the feed of ruminants, preventing metha nogenesis and increasing feed efficiency. HCE is used in metal and alloy production, mainly in refining aluminum alloys. It is also used for removing impurities from molten metals, recovering metals from ores or smelting products and improving the quality of various metals and alloys. HCE is contained in pyrotechnics. It inhibits the explosive ness of methane and the combustion of ammonium perchlo rate. Smoke containing HCE is used to extinguish fires. HCE has various applications as a polymer additive. It has flameproofing qualities, increases sensitivity to radiation crosslinking, and is used as a vulcanizing agent. Added to polymer fibers, HCE acts as a swelling agent and increases affinity for dyes.

Carcinogenicity

Hexachloroethane is reasonably anticipated to be ogen based on sufficient evidence of carcinogenicit a human carciny from studies in experimental animals.

Environmental Fate

Biological. Under aerobic conditions or in experimental systems containing mixed cultures, hexachloroethane was reported to degrade to tetrachloroethane (Vogel et al., 1987). In an uninhibited anoxic-sediment water suspension, hexachloroethane degraded to tetrachloroethylene. The reported half-life for this transformation was 19.7 min (Jafvert and Wolfe, 1987). When hexachloroethane (5 and 10 mg/L) was statically incubated in the dark at 25 °C with yeast extract and settled domestic wastewater inoculum for 7 d, 100% biodegradation with rapid adaptation was observed (Tabak et al., 1981).
Photolytic. When an aqueous solution containing hexachloroethane was photooxidized by UV light at 90–95 °C, 25, 50, and 75% degraded to carbon dioxide after 25.2, 93.7, and 172.0 h, respectively (Knoevenagel and Himmelreich, 1976).
Chemical/Physical. The reported hydrolysis half-life at 25 °C and pH 7 is 1.8 x 109 yr (Jeffers et al., 1989). No hydrolysis was observed after 13 d at 85 °C and pH values of 3, 7, and 11 (Ellington et al., 1987). Similarly, no measureable hydrolysis was observed under neutral and alkaline conditions (Jeffers and Wolfe, 1996).
