This compound is a colorless, mobile liquid with a pleasant smell. It is
practically insoluble in water, but is soluble in alcohol and in most
organic solvents. Ethyl nitrate vapors readily form explosive mixtures
with air even at room temperature; the lower explosion limit is at 3.8%
ethyl nitrate.
Ethyl nitrate explodes when brought into contact with alkali metals.
Ethylphenylurethane
Ethylphenylurethan; éthylphénylinréthane
colorless liquid
empirical formula: C11H15NO2
molecular weight: 193.2
