IMPORTANT DATA
Physical State; Appearance Routes of exposure
OILY COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR. TURNS The substance can be absorbed into the body by inhalation, and by
BROWN ON EXPOSURE TO AIR. ingestion.
Chemical dangers Inhalation risk
The substance decomposes on heating producing flammable and toxic Evaporation at 20/C is negligible; a harmful concentration of airborne
fumes. particles can, however, be reached quickly when dispersed.
Occupational exposure limits Effects of short-term exposure
TLV not established. The substance irritates the eyes, the skin and the respiratory tract.
MAK: Carcinogen category: 2; Germ cell mutagen group: 2 (DFG 2006). Inhalation of the aerosol may cause lung oedema (see Notes). The effects
may be delayed. Medical observation is indicated.
Effects of long-term or repeated exposure
This substance is probably carcinogenic to humans. May cause heritable
genetic damage in humans.
PHYSICAL PROPERTIES
Boiling point (decomposes): 209/C Relative density of the vapour/air-mixture at 20/C (air = 1): 1.001
Melting point: -25/C Flash point: 104/C c.c.
Relative density (water = 1): 1.2 Auto-ignition temperature: 436/C
Solubility in water, g/100 ml at 25/C: 0.7 (poor) Explosive limits, vol% in air: 4.1-?
Vapour pressure, Pa at 20/C: 20 Octanol/water partition coefficient as log Pow: 1.14
Relative vapour density (air = 1): 5.3
ENVIRONMENTAL DATA
The substance is harmful to aquatic organisms.
NOTES
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and
medical observation is therefore essential.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
Rinse contaminated clothes (fire hazard) with plenty of water.
Card has been partially updated in August 2007: see Occupational Exposure Limits.
