FAQ

What are the physical and chemical properties of 1,2-Dibromoethane (CAS: 22581-63-1)?

1,2-Dibromoethane (CAS: 22581-63-1) is a colorless to light yellow liquid with a strong, unpleasant odor. It has a high vapor pressure and low solubility in water. The molecular weight is approximately 177.94 g/mol. It reacts readily with amines and alcohols to form bromo ethers and bromo amines. It is less reactive towards nucleophiles compared to bromoethanes of other positions.

How is 1,2-Dibromoethane (CAS: 22581-63-1) typically synthesized?

1,2-Dibromoethane (CAS: 22581-63-1) is typically synthesized by the reaction of ethylene with bromine in the presence of a Lewis acid catalyst such as iron trichloride or aluminum bromide. The reaction is highly exothermic and selective, yielding a high yield of 1,2-dibromoethane.

What industries use 1,2-Dibromoethane (CAS: 22581-63-1)?

1,2-Dibromoethane (CAS: 22581-63-1) is used in the production of polybrominated diphenyl ethers (PBDEs) for flame retardants, as a raw material for pharmaceuticals, and in the synthesis of other organic compounds. It is also used in the manufacturing of semiconductors and as a solvent in certain chemical processes.

What precautions should be taken when handling 1,2-Dibromoethane (CAS: 22581-63-1)?

When handling 1,2-Dibromoethane (CAS: 22581-63-1), wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work in a well-ventilated area or a fume hood to avoid inhalation. Follow proper spill cleanup procedures and ensure the area is properly ventilated after cleaning. Always consult the Safety Data Sheet (SDS) for detailed safety information and emergency procedures.
