Triethylenediamine CAS 280-57-9

1. Triethylenediamine CAS 280-57-9 is primarily used as a catalyst in the production of polyurethane foams and elastomers.
2. Triethylenediamine serves as a ligand in organometallic chemistry and as a base in organic synthesis.
3. Triethylenediamine is employed in polymer chemistry, pharmaceutical synthesis, and as a curing agent for epoxy resins.

1. Store Triethylenediamine in a tightly sealed, moisture-proof container under an inert atmosphere (e.g., nitrogen) in a cool, dry, well-ventilated area away from heat and incompatible materials.
2. Keep Triethylenediamine away from strong oxidizing agents, strong acids, and moisture to prevent hazardous reactions or degradation.
3. Handle Triethylenediamine with extreme care to avoid skin contact, eye exposure, and inhalation of dust or vapors; it is corrosive and hygroscopic.

1. Immediately isolate the spill area, ensure ventilation, and wear suitable protective equipment (respirator, gloves, goggles) before cleanup.
2. Collect spilled Triethylenediamine with a damp, inert absorbent material. Place the waste in a sealed, labeled hazardous waste container.
3. Neutralize residues carefully with a dilute acid and clean thoroughly. Dispose of waste as hazardous chemical waste according to strict regulations. Prevent entry into drains.

1. Triethylenediamine causes severe skin burns, eye damage, and respiratory tract irritation. It is harmful if swallowed, inhaled, or absorbed through the skin.
2. Triethylenediamine is flammable and its dust can form explosive mixtures with air. It is toxic to aquatic life.
3. Wear full protective equipment (chemical-resistant gloves, goggles, face shield, respirator, lab coat) and work in a fume hood. Strictly consult the Safety Data Sheet.
