Chlorofluorosulfate is a chemical compound from the group of fluorosulfates .

Extraction and presentation

Chlorofluorosulfate can be produced by the reaction of sulfur trioxide with chlorofluoride at low temperatures

${\displaystyle \mathrm {SO_{3}+ClF\longrightarrow ClOSO_{2}F} }$

or by reacting peroxydisulfuryl difluoride with chlorine at 125 ° C under pressure.

${\displaystyle \mathrm {Cl_{2}+S_{2}O_{6}F_{2}\longrightarrow 2\ ClOSO_{2}F} }$

properties

Chlorofluorosulfate is an extremely reactive pale yellow liquid that reacts very violently with water. It decomposes on warming to room temperature and turns red.
