CHEMICAL AND PHYSICAL PROPERTIES

Physical Description 2-chloroethanal appears as a clear colorless liquid with a pungent odor. Flash point about 190 °F. Corrosive to skin and mucous membranes. It is very toxic by inhalation.
Color/Form Colorless liquid [Note: Typically found as a 40% aqueous solution]
Odor Acrid, penetrating odor
Boiling Point 185 °F at 760 mmHg (NTP, 1992)
Melting Point 3 °F (USCG, 1999)
Flash Point 190 °F (NTP, 1992)
Solubility greater than or equal to 100 mg/mL at 66 °F (NTP, 1992)
Density 1.19 at 77 °F (USCG, 1999) - Denser than water; will sink
Vapor Density 2.7 (40% aqueous solution) (NTP, 1992) - Heavier than air; will sink (Relative to Air)
Vapor Pressure 100 mmHg at 113 °F (40% aqueous solution) (NTP, 1992)
LogP 0.37
Stability/Shelf Life The anhydrous substance polymerizes on standing, but reverts to the monomer on distillation.
Autoignition Temperature 88 °C
Decomposition When heated to decomposition it emits toxic fumes of /hydrogen chloride/.
Ionization Potential 10.61 eV
Polymerization Anhydrous substance polymerizes on standing but reverts to the monomer on distillation.
Odor Threshold Odor threshold: 3.0 mg/cu m
Refractive Index Index of refraction: 1.397 at 25 °C
Other Experimental Properties Conversion factors: 1 mg/L equals 309 ppm; 1 ppm equals 3.2 mg/cu m
