Chemical compound
Iodine(I) fluorosulfonate is an inorganic compound of iodine, sulfur, fluorine, and oxygen with the chemical formulaISO3 F . This is a monovalent compound of iodine from the group offluorosulfonates .[ 1] [ 2]
Like the other halofluorosulfonates, iodine(I) fluorosulfonate can be obtained from iodine andperoxydisulfuryl difluoride :[ 3] [ 4]
I2 + S2 O6 F2 → 2ISO3 F Chemical properties [ edit ] Reaction with iodine at 85 °C can convert iodine(I) fluorosulfate totriiodine fluorosulfonate .
I2 + ISO3 F → I3 SO3 F When dissolved incarbon tetrachloride ,iodine monochloride ,peroxydisulfuryl difluoride , andphosgene are formed:[ 5] [ 6]
2ISO3 F + CCl4 → 2ICl + S2 O6 F2 + COCl2 However,carbon dioxide can also be produced instead of phosgene:
4ISO3 F + CCl4 → 4 ICl + 2 S2 O6 F2 + CO2 Physical properties [ edit ] The compound forms black crystals.[ 4]
