Diethylenetriamine is a hardener in epoxy resins of the Bisphenol A type. It has been reported as a sensitizer in ultrasonic baths for cleaning jewels, in synthetic lubricants and in carbonless copy paper.??? ??
Diethylenetriamine is a corrosive yellow liquid and a solvent. It has a strong ammonia odor and is prone to absorbing moisture. It can dissolve in water, acetone, benzene, ether, methanol, but is not soluble in n-heptane.?? ??
Diethylenetriamine is produced by the reaction of ethylene dichloride with ammonia. Diethylenetriamine is used in biological studies, for polyamines inhibition to carbonic anhydrases by anchoring to the zinc-coordinated water molecule.?? ??
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.??? ?? ??
Soluble in water.?? ???
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.????
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).????
Special Hazards of Combustion Products: Irritating vapors are generated when heated.?? ??
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).?? ?? ??
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.Carcinogenicity
DETA has a strong ammonia-like odor, but it does not provide adequate warning of hazardous concentrations.The 2003 ACGIH threshold limit valuetime- weighted average (TLV-TWA) for diethylene triamine is 1ppm (4.2mg/m3) with a notation for skin absorption.
?? ??
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.]?????????? ?? ?? ? ???
