Ethylamine is an organic compound with the formula CH3CH2NH2. This colourless gas has a strong ammonia-like odor. It is miscible with virtually all solvents and is considered to be a weak base, as is typical for amines. Ethylamine is widely used in chemical industry and organic synthesis.

Stability

Stable. Highly flammable. Incompatible with oxidizing agents, alkali metals, alkaline earth metals, acids, many reactive organic and inorganic compounds. Reacts with or disssolves most types of paint, plastic and rubber.

Toxicology

Skin, eye and respiratory irritant. Corrosive - may cause burns to the eye. Harmful if swallowed or inhaled. Very destructive of mucous membranes. Typical STEL 20 ppm.

Personal protection

Safety glasses, good ventilation, butyl rubber gloves.

STORAGE

Fireproof. Cool.

PHYSICAL STATE; APPEARANCE:

COLOURLESS COMPRESSED LIQUEFIED GAS , WITH PUNGENT ODOUR.

PHYSICAL DANGERS:

The gas is heavier than air and may travel along the ground; distant ignition possible.

CHEMICAL DANGERS:

The substance decomposes on heating producing toxic gases including nitrogen oxides. The solution in water is a strong base, it reacts violently with acid and is corrosive. Reacts violently with acid, strong oxidants and organic compounds causing fire and explosion hazard. Attacks many non-ferrous metals and plastics.

OCCUPATIONAL EXPOSURE LIMITS

TLV: 5 ppm; 9.2 mg/m3 (as TWA) (ACGIH 1993-1994).
TLV (as STEL): 15 ppm; 27.6 mg/m3 (ACGIH 1993-1994).

ROUTES OF EXPOSURE:

The substance can be absorbed into the body by inhalation, through the skin and by ingestion.

INHALATION RISK:

A harmful concentration of this gas in the air will be reached very quickly on loss of containment.

EFFECTS OF SHORT-TERM EXPOSURE:

The substance severely irritates the eyes, the skin and the respiratory tract.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

The substance may have effects on the kidneys and lungs , resulting in tissue lesions.

ENVIRONMENTAL DATA

This substance may be hazardous to the environment; special attention should be given to fish.

Ethylamine is also supplied commercially in the form of 70% aqueous solution (UN number: 2270). Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.

Ethylamine is a chemical used mainly in the manufacture of dyes, rayon, rocket propellant, as a fuel additive and in leather-tanning and cellulose treatment. Ingestion and other exposures to the chemical can cause various symptoms.

The type and severity of symptoms varies depending on the amount of chemical involved and the nature of the exposure.
