1112tetrachloroethane

1,1,2,2-Tetrachloroethane, also known as acetylene tetrachloride, is a chlorinated hydrocarbon with the chemical formula C2H2Cl4. It is a colorless, dense liquid with a sweetish odor. The compound is a non-flammable substance. It is produced by the chlorination of acetylene or ethylene. 1,1,2,2-Tetrachloroethane was historically used as a solvent for resins, gums, waxes, and as a degreasing agent. It was also employed in the production of other chlorinated hydrocarbons, such as trichloroethylene and tetrachloroethylene.

Due to its toxicity, the use of 1,1,2,2-tetrachloroethane has been significantly restricted in many countries. Exposure can occur through inhalation, skin absorption, or ingestion. It is known to be a potent hepatotoxin, meaning it can cause damage to the liver. Symptoms of exposure can include nausea, vomiting, abdominal pain, jaundice, and liver failure. Chronic exposure may lead to more severe liver damage and other health problems. Environmental concerns also exist, as chlorinated hydrocarbons can persist in the environment and pose risks to ecosystems. Safer alternatives are now widely used for applications where 1,1,2,2-tetrachloroethane was once employed.
