Octafluoropropane (C3F8) RC 218, PFC 218
R218 is a fluorocarbon non-flammable greenhouse gas that can be produced either by electrochemical fluorination or by the Fowler process using cobalt fluoride. PERFLUOROPROPANE is a colorless, odorless gas.
R218,RC 218, PFC 218 is a special low-temperature refrigerant, usually as a component for mixing low-temperature mixed refrigerant; octafluoropropane, alias: perfluoropropane, ) Is mainly used in microelectronics industry plasma etching, and device surface cleaning, carbon isotope separation of working fluid, medical gas, gas insulation.
|PERFLUOROPROPANE Usage And Synthesis|
|General Description||PFC 218 is a colorless, odorless gas. PFC 218 is relatively inert. The mixture is nonflammable and nontoxic, though asphyxiation may occur because of displacement of oxygen. Exposure of the container to prolonged heat or fire can cause PFC 218 to rupture violently and rocket.|
|Reactivity Profile||PFC 218 is chemically inert in many situations, but can react violently with strong reducing agents such as the very active metals and the active metals. They suffer oxidation with strong oxidizing agents and under extremes of temperature.|
|Health Hazard||Vapors may cause dizziness or asphyxiation without warning. Vapors from liquefied gas are initially heavier than air and spread along ground. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire may produce irritating, corrosive and/or toxic gases.|
|Fire Hazard||Some may burn but none ignite readily. Containers may explode when heated. Ruptured cylinders may rocket.|

RC 218, PFC 218
R218 In the electronics industry, octafluoropropane is mixed with oxygen and used as a plasma etching material for SiO2 layers in semiconductor applications, as oxides are selectively etched versus their metal substrates.
In medicine, octafluoropropane may compose the gas cores of microbubble contrast agents used in contrast-enhanced ultrasound. Octafluoropropane microbubbles reflects sound waves well and are used to improve the ultrasound signal backscatter. It is also used in pars plana vitrectomy procedures where a retina hole or tear is repaired. The gas acts to provide a long-term tamponade, or plug, of a retinal hole/tear and allows re-attachment of the retina to occur over the following several days post-op.
Under the name R-218, octafluoropropane is used in other industries as a component of refrigeration mixtures.
It has featured in some plans for terraforming Mars.
