Sulfur oxide tetrafluoride is a chemical compound from the group of fluorides .

Extraction and presentation

Sulfur oxide tetrafluoride can be obtained by reacting thionyl fluoride with bromopentafluoride at 280 ° C or by reacting thionyl fluoride with fluorine.

{\ displaystyle {\ ce {5 SOF2 + 2 BrF5 -> 5 SOF4 + Br2}}}

{\ displaystyle {\ ce {SOF2 + F2 -> SOF4}}}

It is also possible to display it by reacting sulfur tetrafluoride with oxygen at 200 ° C. and nitrogen dioxide as a catalyst .

{\ displaystyle \ mathrm {2 \ SF_ {4} + O_ {2} \ longrightarrow 2 \ SOF_ {4}}}

properties

Sulfur oxide tetrafluoride is a colorless, pungent smelling gas. It reacts with water to form sulfuryl fluoride and hydrogen fluoride, generating a lot of heat :

{\ displaystyle {\ ce {SOF4 + H2O -> SO2F2 + 2 HF}}}

It absorbs caustic soda completely.
