AdvanSix N,N'Di-tert-butylethylenediamine (DBEDA)

AdvanSix N,N'Di-tert-butylethylenediamine (DBEDA) is a clear, light yellow liquid with an ammonia-like odor that serves as a crucial component in polymer manufacturing. Miscible in ethanol, it has the potential to form a solid hydrate when in contact with water. While stable under recommended storage conditions, caution is necessary due to its flammability when exposed to heat or ignition sources.

Storage & Handling

Handling Recommendations
  • Keep containers closed when not in use.
  • Open containers slowly to allow any excess pressure to vent.
  • Keep away from heat, sparks, flame, or other sources of ignition.
  • Protect small containers from physical damage.
  • Use proper electrical grounding and bonding procedures when loading, unloading, and transferring.
  • Use spark-resistant tools.
  • Electrical equipment and circuits in all storage and handling areas must conform to requirements of national electrical code (Articles 500 and 501) for hazardous location.
