1. Properties of Octafluorocyclobutane:

• Chemical Formula: C₄F₈
• Molecular Weight: 200.03 g/mol
• Physical State: Colorless, odorless gas under standard conditions.
• Boiling Point: -5.8°C (21.6°F)
• Melting Point: -40°C (-40°F)
• Density: Approximately 1.6 g/L as a gas at 25°C.
• Solubility: Insoluble in water but soluble in organic solvents.

2. Reactivity and Chemical Behavior:

• Stability: Chemically inert under normal conditions due to the strength of C-F bonds.
• Thermal Stability: Remains stable over a wide temperature range but can decompose under extreme heat.
• Reactivity: Resistant to most chemical reactions, including acids and bases.

3. Applications of Octafluorocyclobutane:
Electronics Industry: Used as a plasma etching gas in semiconductor manufacturing. Employed in the production of printed circuit boards (PCBs).
Refrigerants and Propellants: Occasionally used in specialized refrigeration systems. Utilized as a propellant in aerosol products.
Fire Suppression: Serves as an extinguishing agent in fire suppression systems.
Medical Applications: Investigated as a contrast agent in diagnostic imaging.
Gas Insulation: Functions as an insulating gas in high-voltage equipment.

4. Safety and Handling:

• Hazards:
  • Inhalation: May cause dizziness, headache, or respiratory irritation if inhaled in large quantities.
  • Environmental Impact: Classified as a greenhouse gas with a high global warming potential (GWP).
• Protective Measures:
  • Use in well-ventilated areas to minimize inhalation risks.
  • Wear appropriate protective equipment, including gloves and goggles.


• 5. Storage:
  • Store in tightly sealed cylinders in a cool, dry place away from heat sources or direct sunlight.
  • Ensure storage complies with local regulations for pressurized gases.
