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.
Physical dangers
Inhalation risk
The vapour is heavier than air and may travel along the ground;
distant ignition possible. As a result of flow, agitation, etc., A harmful contamination of the air can be reached rather quickly
electrostatic charges can be generated. on evaporation of this substance at 20/C.
Chemical dangers
Reacts violently with oxidants causing fire and explosion hazard.
Attacks plastic.
Occupational exposure limits
TLV: (as hexane isomers) 500 ppm as TWA; 1000 ppm as
STEL; (ACGIH 2004).
MAK: 200 ppm, 720 mg/m3; Peak limitation category: II(2);
Pregnancy risk group: IIc; (DFG 2004).
PHYSICAL PROPERTIES
Boiling point: 63.3/C Relative vapour density (air = 1): 2.97
