Useful:
  • Chemical Classes:Toxic Gases & Vapors -> Corrosive Gases
  • Canonical SMILES:FS(F)(F)F
  • Inhalation Risk:A harmful concentration of this gas in the air will be reached very quickly on loss of containment.
  • Effects of Short Term Exposure:The substance is corrosive to the eyes, skin and respiratory tract. The liquid may cause frostbite. Inhalation of this gas may cause lung oedema.
  • Effects of Long Term Exposure:The substance may have effects on the bones and teeth. This may result in fluorosis.
  • Uses Compounds of interest in this group include sulfur hexafluoride (SF6) used as an electrical insulating material in circuit breakers, cables, capacitors, and transformers, and its degradation products, which are produced when electrical arcing occurs. The specific compounds produced depend on the arcing conditions. In anaerobic and anhydrous circumstances, sulfur tetrafluoride (SF4) is produced; if moisture is present, the tetrafluoride may hydrolyze to form thionyl fluoride (SOF2) and HF. Sulfuryl fluoride (SO2F2), disulfur decafluoride (S2F10), sulfur pentafluoride (SF5), and sulfur dioxide are also formed from sulfur hexafluoride. Some of these compounds are also produced as contaminants in the commercial production of sulfur hexafluoride by burning sulfur in fluorine gas, for example, sulfur tetrafluoride and disulfur decafluoride, as well as sulfur monofluoride (S2F2). As a fluorinating agent in the production of water- and oil-repellant materials and lubricity improvers; found as a degradation product of sulfur hexafluoride. Selective fluorinating agent.
Technology Process of Sulfur tetrafluoride

There total 120 articles about Sulfur tetrafluoride which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:
Guidance literature:
In neat (no solvent); byproducts: OF2; introduction of F2 into steel chamber, sulfur in compartments; detailed description of apparatus and handling given;; first passing through Ni (or Monel) tube (400°C); second Cu column (H2O sprayed); passed into steel column (containing carbon/Fe shavings; aq. NaOH sprayed); dried in column (containing solid NaOH, BaO or P2O5);;
Guidance literature:
In further solvent(s); byproducts: (FCN)3; reactn. of a soln. of dirhodane in FCl2C-CClF2 with diluted F2 (F2:N2 0 1:10); cooled down to -183°C; solvent removed by condensation; mixt. condensed to aq. KOH-soln. at room temp. to remove SF4, SOF and (FCN)3; sepn. by fractionated condensation at -127°C, -140°C, -196°C;
