Abstract
Described herein are methods for the bromine-facilitated synthesis of fluoro-sulfur compounds, that include SF4, SF5Cl, SF5Br and SF6. The methods described herein generally require lower temperature and pressure, produce higher yields, require less time, do not use corrosive or costly reactants and solvents that are commonly used in the synthesis of the fluoro-sulfur compounds, and do not produce deleterious waste products when compared to previously-used methods.
Claims17
A method comprising:
- admixing a Br2 reactant, an SF4 reactant, and a CoF3 reactant, thereby initiating a reaction to produce an amount of SF6.
A method comprising:
- admixing a Br2 reactant, an SF4 reactant, and a metal fluoride reactant, thereby initiating a reaction that produces to produce an amount of SF6 at temperatures from about 10° C. to about 100° C., wherein the metal fluoride reactant is selected from CoF3, CeF4, MnF3, PbF4, AgF2, AgF, AuF, or combinations thereof, and the SF6 is produced without adding reactants chosen from F2 SF5Cl, IF5, CIF HF, BrF3, or combinations thereof.
