PHYSICAL PROPERTIES
Boiling point: 77/C Relative density of the vapour/air-mixture at 20/C (air = 1): 1.05
Melting point: -84/C Flash point: -1/C c.c.
Relative density (water = 1): 0.8 Auto-ignition temperature: 481/C
Solubility in water, g/100 ml at 20/C: 7 Explosive limits, vol% in air: 3.0-17.0
Vapour pressure, kPa at 20/C: 11.0 Octanol/water partition coefficient as log Pow: 0.25
Relative vapour density (air = 1): 1.8
ENVIRONMENTAL DATA
The substance is harmful to aquatic organisms.
NOTES
Depending on the degree of exposure, periodic medical examination is suggested.
Exposure to the substance will result in cyanide formation.
Also consult ICSC of a cyanide salt, such as 0671.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
The odour warning when the exposure limit value is exceeded is insufficient.
Rinse contaminated clothes (fire hazard) with plenty of water.
Card has been partly updated in April 2005. See section Occupational Exposure Limits.
