Physical description & handling notes

• Ethylamine appears as a colorless liquid or a gas (boiling point 62 °F) with an odor of ammonia. Flash point less than 0 °F. Density of liquid 5.7 lb / gal. Corrosive to the skin and eyes. Vapors are heavier than air. Produces toxic oxides of nitrogen during combustion. Exposure of the closed container to intense heat may cause it to rupture violently and rocket.
• Ethylamine, aqueous solution, with not less than 50% but not more than 70% ethylamine appears as an aqueous solution of a gas. Odor ranges from fishlike to ammonia-like as the vapor concentration increases. Corrosive to skin and eyes. Less dense than water. Vapors are heavier than air. Produces toxic oxides of nitrogen during combustion.
• Gas Vapor; Liquid
• Colorless gas or water-white liquid (below 62 degrees F) with an ammonia-like odor; Note: Shipped as a liquefied compressed gas; [NIOSH]
• Liquid
• COLOURLESS COMPRESSED LIQUEFIED GAS WITH PUNGENT ODOUR.
