Reactivity Profile · 1 item

CHLORINE PENTAFLUORIDE is a strong oxidizing agent. Nonflammable, but likely to react vigorously on contact with combustible materials. Reacts violently with lithium, calcium. Emits highly toxic fluoride and chloride fumes when heated to decomposition. Extremely vigorous reaction with water, steam, even ice [Pilipovich D. et al., Inorg. Chem., 1967, 6, p. 1918]. Very vigorous reaction with anhydrous nitric acid even at -100 °C [Christie, K. O., Inorg. Chem. 1992, 11, p. 1220].

Air and Water Reactions · 1 item

Reacts with water or moisture in the air to produce corrosive hydrofluoric acid and toxic chlorine gas. Interaction with ice at -100 °C, or with water vapor above 0 °C is extremely vigorous (Christe, K.O. Inorg. Chem. 1972 11, 1220). Hydrochloric acid fumes might also be generated upon reaction with water.
