- Handling Precautions:
- Use only in fume hoods or enclosed systems with proper ventilation.
- Avoid exposure to skin, eyes, and respiratory system.
Handling & Storage
- Storage Conditions:
- Store in tightly sealed, moisture-free cylinders under dry, inert gas (argon or nitrogen).
- Keep in a well-ventilated, temperature-controlled storage area.
- Personal Protective Equipment (PPE):
- Chemical-resistant gloves, safety goggles, and protective clothing.
- Use gas detection systems and emergency response protocols.
- First Aid Measures:
- Inhalation: Move to fresh air immediately; seek medical attention.
- Skin/Eye Contact: Flush with large amounts of water and seek emergency care.

Boron Trifluoride (BF₃)는 무색, 유독성이며 강한 자극 냄새를 지닌 고활성 가스입니다. 강력한 루이스 산으로서 BF₃는 유기 합성, 중합 및 석유 화학 처리에서 촉매로 널리 사용됩니다. 수분과 쉽게 반응하여 불수소산(HF)과 붕산 유도체를 형성하므로 제어된 조건에서 취급하는 것이 필수적입니다. 높은 반응성과 배위 능력으로 인해 BF₃는 에테르, 아민 및 알코올과 안정한 복합체를 형성하여 산업 및 실험실 응용 분야를 넓혀줍니다.
