Introduction
Octafluoropane (also known as HFC-218) is a colorless and odorless gas.
Nature:
Insoluble in water, soluble in most organic solvents.
Usage:
1. Sonar detection: The low reflectivity and high absorption of octafluoropropane make it an ideal medium for underwater sonar systems.
2. Fire extinguishing agent: Due to its non flammable and non-conductive nature, octafluoropropane is widely used in fire extinguishing systems for electronic and high-value equipment.
Method:
The preparation method of octafluoropropane is usually through the reaction of hexafluoroacetyl chloride (C3F6O).
Security information:
1. Octafluoropane is a high-pressure gas that needs to be stored and used to prevent leakage and sudden release.
2. Avoid contact with fire sources to prevent fire or explosion.
3. Avoid inhaling octafluoropropane gas, which can cause suffocation.
4. Octafluoropane is lethal and destructive, so personal protection should be taken into account during operation, such as wearing appropriate respiratory equipment and chemical protective clothing.
