Bromodichloromethane is a chemical compound from the group of aliphatic, saturated halogenated hydrocarbons (more precisely trihalomethanes ).
Occurrence
Bromodichloromethane occurs as a by-product of the chlorination of water. Bromodichloromethane is not used industrially.
Properties and use
When bromodichloromethane is heated in the presence of oxygen or reducing agents and metals as a catalyst , it slowly decomposes with the formation of acidic gases (HCl, HBr). This reaction can be used to produce long-life halogen lamps .
safety instructions
Bromodichloromethane is classified as carcinogen category 2 and germ cell mutagen category 3B.
