sulfur hexafluoride Vacuum for Maintenance

Disclosed is a method for an energy-efficient improvement in the production of sulfur hexafluoride, and eliminates the generation of other byproducts. The process is an oxidative fluorination of sulfur tetrafluoride by CoF 3 /F 2, where CoF 3 is solid stationary phase that can be regenerated.
