1112tetrabromoethane

1,1,2,2-Tetrabromoethane, also known as acetylene tetrabromide, is a halogenated hydrocarbon with the chemical formula C2H2Br4. It is a dense, colorless to pale yellow liquid with a sweet odor. It is insoluble in water but soluble in organic solvents such as ethanol and ether. Historically, 1,1,2,2-tetrabromoethane has been used as a solvent and as a heavy liquid for mineral separation due to its high density. Its high density also led to its use as a vibration damping material and as an additive in certain plastics.

The synthesis of 1,1,2,2-tetrabromoethane typically involves the addition of bromine to acetylene. This reaction is exothermic and requires careful control. Due to its properties, it has also found application as a fluid in barometers and in certain electrical equipment. However, its use has declined significantly due to environmental and health concerns.

1,1,2,2-Tetrabromoethane is considered toxic and can cause irritation to the skin, eyes, and respiratory tract. Exposure can lead to central nervous system depression, liver and kidney damage. Consequently, handling requires appropriate protective measures. Its persistence in the environment and potential for bioaccumulation are also factors contributing to its reduced usage. It is classified as a hazardous substance and its disposal is regulated.
