Diethylenetriamine CAS 110-40-0 Use

● Chemical Engineering and Materials Synthesis

   ○ Epoxy resin curing agent: As an efficient curing agent, it is used in electronic insulating materials, coatings and adhesives to enhance mechanical strength and heat resistance (heat distortion temperature 95-124 ℃).

   ○ Organic synthesis intermediates: synthetic polyamide resins, ion exchange resins, surfactants and lubricating oil additives.

   ○ Gas purifying agent: Removes acidic gases such as CO₂ and is used for the purification of natural gas and industrial gases.


● Metal processing and electroplating

   ○ Metal chelating agents: Used in hydrometallurgy to separate heavy metals (such as copper and nickel) and increase metal recovery rates.

   ○ Cyanide-free electroplating additive: As a diffuser and brightener, it can replace cyanide processes, is environmentally friendly and provides uniform coating.


● Other industrial fields

   ○ Oilfield chemicals: Viscosity reducers (to lower the viscosity of crude oil) and water blocking agents (to reduce formation water infiltration).

   ○ Textile and papermaking: Fabric finishing agents enhance wear resistance, and paper strengthening agents improve tear strength.

   ○ Nuclear industry: Chelating radioactive ions (such as uranium and plutonium), and safely handling nuclear waste.


Diethylenetriamine CAS 110-40-0 safety

Health and environmental risks

  ● Toxicity

     ○ Acute toxicity: Oral LD₅₀=2080 mg/kg (low toxicity) in rats, transdermal LD₅₀=1090 mg/kg in rabbits.

     ○ Irritation: Skin contact can cause burns, vapor can irritate the respiratory tract (may cause pulmonary edema), and eye contact can lead to blindness.

     ○ Sensitization: Approximately 1% of those exposed develop allergic dermatitis or asthma.

     ○ Environmental impact: Toxic to aquatic organisms. The allowable concentration in surface water is ≤0.2 mg/L (Soviet Union standard).


Operation and storage requirements

   ● Protective measures

     ○ When operating, gas masks, acid and alkali resistant suits, goggles and rubber gloves must be worn.

     ○ Avoid contact with water (releases heat upon contact with water) and oxidants (may cause combustion).


Storage conditions

   ● Store sealed in a cool and well-ventilated place (≤30℃), protected from moisture by inert gas (nitrogen).


Leakage treatment

    ● Adsorb with sand or vermiculite. Do not rinse with water. When there is a large-scale leakage, it should be contained in dikes and incinerated for disposal.
