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.

IHL-RAT LCLO 23000 ppm/4h
SKN-RBT LD50 390 mg kg-1
IVN-RBT LDLO 350 mg kg-1Risk phrases R12 R20 R22 R34 R36 R37 R38.
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.
