PHYSICAL PROPERTIES
Boiling point: 146/C Vapour pressure, Pa at 20/C: 647
Melting point: -44/C Relative vapour density (air = 1): 5.8
Relative density (water = 1): 1.59 Relative density of the vapour/air-mixture at 20/C (air = 1): 1.03
Solubility in water, g/100 ml at 20/C: 0.29 Octanol/water partition coefficient as log Pow: 2.39
ENVIRONMENTAL DATA
The substance is toxic to aquatic organisms.
NOTES
Use of alcoholic beverages enhances the harmful effect.
The odour warning when the exposure limit value is exceeded is insufficient.
Do NOT use in the vicinity of a fire or a hot surface, or during welding.
Card has been partly updated in October 2005. See section Storage.
