1422 ALLYL PROPYL DISULFIDE
IMPORTANT DATA
Physical State; Appearance Routes of exposure
PALE YELLOW LIQUID, WITH PUNGENT ODOUR. The substance can be absorbed into the body by inhalation and
by ingestion.
Chemical dangers
Inhalation risk
The substance decomposes on burning producing sulfur oxides.
Reacts with oxidants. A harmful contamination of the air can be reached rather quickly
on evaporation of this substance at 20/C.
Occupational exposure limits
Effects of short-term exposure
TLV: 2 ppm as TWA, 3 ppm as STEL; Intended change: 0.5
ppm SEN; (ACGIH 2004). The substance is irritating to the eyes, the skin and the
MAK: 2 ppm, 12 mg/m3 Peak limitation category: I(1); (DFG respiratory tract
2004).
PHYSICAL PROPERTIES
Boiling point at 2.1kPa: 66-69/C Vapour pressure, Pa at 20/C: 50
Melting point: -15/C Relative vapour density (air = 1): 5.1
Relative density (water = 1): 0.9 Relative density of the vapour/air-mixture at 20/C (air = 1): 1.00
Solubility in water: none Flash point: 56/C
