Duofuduo: Patent for “A method of recovering sulfur during the production of hydrofluoric acid to produce high-purity sulfur hexafluoride”

2026-06-08View Original

Thread Content

The 25th National \"Safety Production Month\" in 2026: Everyone should talk about safety and know how to handle emergencies; identify and address potential risks and hazards. -------------------------------------------------- Recently, **data from the Intellectual Property Office shows that Duofuduo New Materials Co., Ltd. has applied for a patent titled \"A method for recovering sulfur during the production of hydrofluoric acid in order to produce high-purity sulfur hexafluoride.\" The application publication number is CN122102062A, and the application date is February 2026. The patent abstract states that this invention falls within the field of technology related to the production of high-purity sulfur hexafluoride. It specifically relates to a method for producing high-purity sulfur hexafluoride by recovering sulfur during the production process of hydrofluoric acid. Through the electrolysis of hydrofluoric acid to generate fluorine-containing active ions, it is possible to produce sulfur hexafluoride gas directly from elemental sulfur using these fluorine-containing active ions, without the need for sulfur removal. High-purity sulfur hexafluoride gas is then obtained through distillation, thereby enabling the reuse of sulfur resources, improving production efficiency and product purity, while also reducing energy consumption and environmental pollution.
