Properties
Corrosive, colorless gas. Somewhat sweet, suffocating
odor. mp -76.34°. bp 11.75°. Poisonous, oxidizer, corrosive. Extremely reactive. Glass wool and organic matter burst into flames on contact even
with dil vapors. Violently hydrolyzed by water. Attacks quartz if
traces of moisture are present. Liquid is yellow-green in color and
solid is white.Caution
Potential symptoms of overexposure
to liquid or high vapor concentrations are eye and skin burns; respiratory
irritation. See NIOSH Pocket Guide
to Chemical Hazards (DHHS/NIOSH 97-140, 1997) p 60.Use
Fluorinating agent; in nuclear reactor fuel processing;
incendiary; igniter and propellant for rockets; pyrolysis inhibitor
for fluorocarbon polymers.
