Sensitivity, selectivity, modest cost, and active medium Enviro-whiner hissy fit CF3I. Large scale apparatus using perfluorobutane is exciting.
Like 100,000 gallons of perchloroethylene buried 4900 feet deep, it lacks the looming visceral thrill of dropping a hex nut and blasting South Dakota into space. Uncle Al recommends a Media darling active medium: iodine heptafluoride, IF7.
CF3I,
bp -32.5°C, d = 2.36 g/ml
@ 25°C, d = 2.06 g/ml liquid
29.092 wt-% F, 64.777 wt-% I
IF7,
mp = 4.5 C d = 2.7 g/cm^3 (solid)
bp = 4.77 C, colorless
51.171 wt-% F, 48.829 wt-% I
Incompatible with Pyrex, fused silica (Teflon AF windows?), and most metals (Monel?); expensive, corrosive, toxic, malodorous. IF7 has it all!
