CHEMICAL AND PHYSICAL PROPERTIES

Physical Description Ethyl nitrite, solution appears as a clear colorless to yellow liquid with a pleasant odor. Flammable over a wide range of vapor-air concentrations. Flash point -31 °F. Less dense than water and insoluble in water. Vapors are heavier than air and narcotic in high concentrations. Produces toxic oxides of nitrogen during combustion.
Color/Form Colorless or yellowish, clear liquid
Odor SWEET, RUM-LIKE ODOR
Taste FRUITY TASTE
Boiling Point 63 °F at 760 mmHg (USCG, 1999)
Melting Point -58 °F (USCG, 1999)
Flash Point -31 °F (USCG, 1999)
Solubility Slightly soluble in water; decomposes in water; miscible with alcohol, ether
Density 0.9 at 59 °F (USCG, 1999) - Less dense than water; will float
Vapor Density 2.6
