Diamond Hazard Value Description
3 0
HEALTH   3 Short exposure could cause serious temporary or moderate residual injury (e.g. liquid hydrogen, sulfuric acid, calcium hypochlorite, hexafluorosilicic acid)
FIRE  1 Materials that require considerable preheating, under all ambient temperature conditions, before ignition and combustion can occur. Includes some finely divided suspended solids that do not require heating before ignition can occur. Flash point at or above 93.3 °C (200 °F). (e.g. mineral oil, ammonia)
REACT   0 Normally stable, even under fire exposure conditions, and is not reactive with water (e.g. helium,N2)

Diethylenetriamine Chemical Properties,Uses,Production

Chemical Properties

colourless liquid

Production Methods

Diethylenetriamine is produced by the reaction of ethylene dichloride with ammonia.

General Description

A yellow liquid with an ammonia-like odor. Less dense than water. Corrosive to metals and tissue. Vapors heavier than air. Burns, although possibly difficult to igntie. Toxic oxides of nitrogen produced during combustion. Used as a solvent for plastics and dyes and in chemical synthesis.

Air & Water Reactions

Soluble in water.

Reactivity Profile

Diethylenetriamine neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.

Health Hazard

Prolonged breathing of vapors may cause asthma. Liquid burns skin and eyes. A skin rash can form.

Health Hazard

Brief contact with concentrated diethylenetriamine can produce severe local injury to the eyes and skin resembling the effect from strong base. Human subjects are susceptible to sensitization responses either as dermatitis or an asthma-like response. A time-weighted average of 1 p.p.m. is recommenced for diethylenetriamine (ACGIH 1986).

Fire Hazard

Flash Point (°F): 200 ℃; Flammable Limits in Air (%): 1-10; Fire Extinguishing Agents: Water spray, alcohol foam, carbon dioxide, or dry chemical; Fire Extinguishing Agents Not To Be Used: Water or foam may cause frothing; Special Hazards of Combustion Products: Irritating vapors are generated when heated; Behavior in Fire: Not pertinent; Ignition Temperature (°F): 676; Electrical Hazard: Not pertinent; Burning Rate: Data not available.

Fire Hazard

Special Hazards of Combustion Products: Irritating vapors are generated when heated.

Chemical Reactivity

Reactivity with Water No reaction; Reactivity with Common Materials: No hazardous reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Flush with water; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.

Industrial uses

Diethylenetriamine is used as an intermediate in the production of reactive polyamide resins, and in the production of aminoamides and imidazolines from fatty acids. It is also used in the production of paper wet strength resins and piperazine. Diethylenetriamine serves as a solvent for sulfur, acid gases, resins and dyes (HSDB 1989).

Contact allergens

Diethylenetriamine is a hardener in epoxy resins of the Bisphenol A type. It has been reported to be a sensitizer when used in an ultrasonic bath for cleaning jewels, in synthetic lubricants, or in carbonless copy paper.

Safety Profile

Poison by skin contact and intraperitoneal routes. Moderately toxic by ingestion. Corrosive. A severe skin and eye irritant. High concentration of vapors causes irritation of respiratory tract, nausea, and vomiting. Repeated exposures can cause asthma and sensitization of skin. Combus uble when exposed to heat or flame; can react with oxidizing materials. Mxture with nitromethane is a shock-sensitive explosive. Ignites on contact with cellulose nitrate of high surface area. To fight fire, use alcohol foam. When heated to decomposition it emits toxic fumes of NOx. See also AMINES.


Diethylenetriamine is readily absorbed through the gastrointestinal tract and 96% of the administered dose is excreted within 48 h (USEPA 1983a). Roughly equal amounts are excreted in the feces and urine with at least 4 metabolites being detected (but not identified) in the latter. Only a small proportion (<2%) was recovered as expired carbon dioxide. Any residual remaining in the animal was found primarily in kidney, liver, bladder and large intestine.

Purification Methods

Dry the amine with Na and distil, preferably under reduced pressure, or in a stream of N2. [Beilstein 4 IV 1284.]
