Webmodifier. Le dichlorométhane ( DCM) ou chlorure de méthylène (dénommé R30 dans la liste des réfrigérants ), est un composé organique se présentant à température ambiante comme un liquide incolore et volatil émettant une odeur douceâtre relativement forte pouvant mettre certaines personnes mal à l'aise. WebDibromomethane is prepared commercially from dichloromethane via bromochloromethane: 6 CH 2 Cl 2 + 3 Br 2 + 2 Al → 6 CH 2 BrCl + 2 AlCl 3 CH 2 Cl 2 + HBr → CH 2 BrCl + HCl. The latter route requires aluminium trichloride as a catalyst. The bromochloromethane product from either reaction can further react in a similar manner:
