Pentachloroethane

Pentachloroethane is a chlorocarbon with the formula C2Cl5H. It is a colorless liquid with a sweet, pleasant odor. It is used as a solvent for oil and grease, in metal cleaning, and in the separation of coal from impurities.

Chemical Properties

Pentachloroethane is a chlorinated hydrocarbon that has been used as a solvent, in the production of fluorocarbons, and in the separation of coal from impurities. It is a dense, non-flammable liquid that is stable under normal conditions. It is not found naturally in the environment and is produced by human activities.

Health Effects

Exposure to pentachloroethane can occur through inhalation, skin contact, and ingestion. It can cause irritation to the eyes, skin, and respiratory tract. Acute exposure can result in central nervous system depression and liver and kidney damage. Chronic exposure can lead to liver and kidney damage, as well as damage to the lungs and nervous system.

Environmental Impact

Pentachloroethane is a persistent organic pollutant, meaning it does not break down easily in the environment and can accumulate in living organisms. It can be transported long distances in the air and can contaminate soil and water. It is toxic to aquatic life and can cause long-term adverse effects in the aquatic environment.

Regulation

Due to its toxicity and persistence in the environment, the use and production of pentachloroethane is regulated in many countries. In the United States, it is classified as a hazardous substance under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), and its release to the environment is subject to reporting requirements.
