IMPORTANT DATA
Physical State; Appearance Routes of exposure
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR. The substance can be absorbed into the body by inhalation of
its vapour and by ingestion.
Physical dangers
Inhalation risk
The vapour is heavier than air and may travel along the ground;
distant ignition possible. A harmful contamination of the air can be reached very quickly
on evaporation of this substance at 20/C.
Chemical dangers
Effects of short-term exposure
The substance decomposes on burning producing toxic gases
including nitrogen oxides. The solution in water is a medium The substance is corrosive to the eyes, the skin and the
strong base. Reacts violently with acids and oxidants. respiratory tract. Corrosive on ingestion. Inhalation of the
substance may cause lung oedema (see Notes). The effects
may be delayed. Medical observation is indicated.
Occupational exposure limits
TLV not established.
MAK: 5 ppm, 15 mg/m3; skin absorption (H); Peak limitation
category: I(2); Pregnancy risk group: IIc; (DFG 2004).
PHYSICAL PROPERTIES
Boiling point: 68-69/C Relative density of the vapour/air-mixture at 20/C (air = 1): 1.2
Melting point: -85/C Flash point: -9.0/C c.c.
Relative density (water = 1): 0.72 Auto-ignition temperature: 378/C
Solubility in water: miscible Explosive limits, vol% in air: 3.4-9
Vapour pressure, kPa at 18.8/C: 13.3 Octanol/water partition coefficient as log Pow: 0.73
Relative vapour density (air = 1): 2.5
ENVIRONMENTAL DATA
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 are therefore essential.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
