BROMODICHLOROMETHANE

ICSC: 0393

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS LIQUID. Physical dangers The vapour is heavier than air. Chemical dangers Decomposes on contact with hot surfaces or flames. This produces toxic and corrosive gases including hydrogen bromide and hydrogen chloride. Reacts with strong bases, strong oxidants and magnesium.	Formula: CHBrCl₂ Molecular mass: 163.8 Boiling point: 90°C Melting point: -57°C Density: 1.9 g/cm³ Solubility in water, g/100ml at 20°C: 0.45 (poor) Vapour pressure, kPa at 20°C: 6.6 Relative vapour density (air = 1): 5.6 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.3 Octanol/water partition coefficient as log Pow: 2

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by ingestion. Effects of short-term exposure	Inhalation risk A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C. Effects of long-term or repeated exposure Ingestion may cause effects on the kidneys and liver. This may result in impaired functions. This substance is possibly carcinogenic to humans.
