01 · Identification
What Ethylamine is
Ethylamine is a colorless gas or water-white liquid (below 62 degrees F) [Shipped as a liquefied compressed with an ammonia odor. It boils at 16.6 °C, melts at -81.2 °C, is miscible with water.
Under the GHS it carries the signal word Danger. It is classed as flammable agents - 4th degree.

Reactivity
Sensitive to heat. Reacts vigorously with oxidizing agents. Incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Incompatible with cellulose nitrate. Flammable gaseous hydrogen is generated in combination with strong reducing agents, such as hydrides. Also incompatible with oxidizing agents. A chemical base. Neutralizes acids to form salts plus water in an exothermic reaction Dissolves most paints, plastics and rubber (NTP, 1992).
