Important Data
|
Physical State; Appearance:
CLEAR COLOURLESS LIQUID,
TURNING BROWN UPON STANDING
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
The vapour is heavier than air
and may travel along the ground; distant ignition possible.
Chemical Dangers:
The substance can form explosive peroxides upon contact with air.
Reacts violently with oxidants and acids
causing fire and explosion hazard.
Fire hazard upon exposure to heat or flame.
Occupational Exposure Limits:
TLV not established.
MAK: skin absorption (H);
Carcinogen category: 2
(DFG 2008).
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its vapour and
by inhalation of its aerosol, and
through the skin.
Inhalation Risk:
A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C.
Effects of Short-Term Exposure:
The vapour
irritates the respiratory tract.
Inhalation of the vapour may cause lung oedema (see Notes).
Effects of Long-Term or Repeated Exposure:
|
|
Physical
Properties

Melting point: -85.6°C
Relative density (water = 1): 0.94
Solubility in water: poor
|
Relative vapour density (air = 1): 2.3
Flash point: -35°C
Explosive limits, vol% in air: 2.3-14.3
Octanol/water partition coefficient as log Pow: 1.34

N O T E S
|
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 spray, by a doctor or a person authorized by him/her, should be considered.
An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.
Check for peroxides prior to distillation; eliminate if found.
