AdvanSix Tri-n-propylamine (ΤΡΑ)

AdvanSix Tri-n-propylamine (ΤΡΑ) is a colorless liquid with an ammonia-like odor. It exhibits slight solubility in water and remains stable when stored according to recommended conditions. However, caution is warranted as it can ignite when heated or exposed to an ignition source. TPA is primarily employed in the synthesis of carbon nanotubes for research purposes and also finds utility as a solvent in various applications.

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.
