description
Octafluoropropane (C3F8) is the perfluorocarbon counterpart to the hydrocarbon propane. This non-flammable and non-toxic synthetic substance has applications in semiconductor production and medicine. It is also an extremely potent greenhouse gas.Octafluoropropane can be produced either by electrochemical fluorination or by the Fowler process using cobalt fluoride.
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 reflect sound waves well and are used to improve the ultrasound signal backscatter.It is used in eye surgery, such as pars plana vitrectomy procedures where a retina hole or tear is repaired. The gas provides a long-term tamponade, or plug, of a retinal hole or tear and allows re-attachment of the retina to occur over the several days following the procedure.Under the name R-218, octafluoropropane is used in other industries as a component of refrigeration mixtures.
