Tetrabrromoethane

Tetrabromoethane, also known as acetylene tetrabromide, is a halogenated hydrocarbon with the chemical formula C2H2Br4. It is a dense, colorless to pale yellow liquid at room temperature, though it can decompose and darken over time. Tetrabromoethane is sparingly soluble in water but miscible with many organic solvents like ethanol and ether. Historically, it has found applications as a heavy liquid for mineral separation due to its high density, and in the past, it was used as a fumigant and in x-ray contrast media. However, its use has declined significantly due to its toxicity and environmental concerns.

The compound is synthesized through the addition of bromine to acetylene. Tetrabromoethane is considered toxic and can cause irritation to the skin, eyes, and respiratory tract. Inhalation of vapors can lead to central nervous system depression, and prolonged exposure may affect the liver and kidneys. Due to its hazardous nature, proper handling procedures, including adequate ventilation and personal protective equipment, are essential when working with tetrabromoethane. It is also considered an environmental pollutant.
