PHYSICAL DATA

Boiling point 39-40°C. Freezing point -95°C. Density 1.326. Insoluble in water. Vapor pressure

380 mm at 22°C. Vapor density 2.93. 100% volatile.



APPEARANCE & ODOR

Clear colorless liquid. Strong chloroform-like characteristic odor.



REACTIVITY & CONDITIONS TO AVOID

Stable. Reacts violently with alkali metals. Incompatible with strong oxidizers, strong bases,

amines. Heating to decomposition may give fumes of phosgene. Should not be used in long term

contact with aluminum, zinc or their alloys.



FIRE HAZARDS

May decompose in fire to yield toxic gas (phosgene). Avoid inhalation of fumes.

Firefighters wear SCBA. NFPA #2-1-0.
