Application
As a solvent for fats. Due to its high density, it was used for the separation of minerals. Previously, it was not he who was used for fire extinguishing, but CH2BrCl bromochloromethane (CAS: 74-97-5; https://chem.nlm.nih.gov/chemidplus/rn/74-97-5 ).
Laboratory method for producing bromodichloromethane (CHBrCl2): bromination of chloroform, in the presence of aluminum, significantly less (LD50: mouse oral 4300mg / kg) hazardous bromochloromethane CH2BrCl, anesthetic and fire fighting agent come out of dichloromethane.
