04 · Handling and storage
Storing and handling 2,2'-iminodiethylamine
Storage conditions
Protect containers against physical damage. Store in cool, dark, well-ventilated place away from sources of ignition.
Source: Hazardous Substances Data Bank (HSDB)
Incompatible materials
Explosive solutions of nitromethane in dichloromethane, sensitized by addition of 10-12% of /bis(2-aminoethyl)amine/, retained their sensitivity at -50 °C. Presence of 0-5% of the triamine considerable increases detonation sensitivity of nitromethane.

Reactivity
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.
