Physical and Chemical Properties - Physical State at 15 ‘C and I atm. : Liquid; Molecular Weighc:
133.19; Boiling Point at I atm.: 479.7, 248.7, 521.9; Freezing Point: 108, 42, 315; Critical
Temperature: 750, 399, 612; Critical Pressure: 529, 36, 3.6; specific Gravity: 0.99 at 42°C (liquid);
Vapor (Gas) Density: Not pertinent; Ratio ofSpecifc Heats ofvapor (Gas): Not pertinent; Latent Heat
of Vaporization: 185, 103,4.31; Heat of Combustion: -12,300, -6860, -287; Heat of Decomposition:

Health Hazards Information -Recommended Personal Protective Equipment: Full face mask or amine
vapor mask only if required; clean, body-covering clothing, rubber gloves, apron, boots and face
shield; Symptoms Following Exposure: Vapor concentrations too low to irritate unless exposure is
prolonged. Liquid will burn eyes and skin; General Treatment for Ekposure: INHALATION if ill
effects occur, remove person to fresh air and get medical help. INGESTION: if swallowed and patient
is conscious and not convulsing, promptly give milk or water, then induce vomiting; get medical help.
No specific antidote known. EYES AND SKIN: immediately flush with plenty of water for at least 15
min. For eyes, get medical help promptly. Remove and wash contaminated clothing before reuse;
Toxicity by Inhalation (Threshold Limit Vdue): Not pertinent; Short-Tern Exposure Limits: Not
pertinent; Toxicity by Ingestion: Grade 2; LD,, 0.5 to 5 glkg (rat); Late Toxicity: Data not available;
Vapor (Gas) Irritant Characteristics: Vapors cause moderate irritation such that personnel will find
high concentrations unpleasant. The effect is temporary; Liquid or Solidlm*tant Characteristics: Causes
smarting of the skin and first-degree burns on short exposure and may cause secondary burns on long
exposure; Odor Threshold Data not available.
Fire Hazards - Flash Point (deg. F): 200 OC; I;Iammabe Limits in Air (%): 1.1 (calc.) - 5.4 (est.);
Fire Extinguishing Agents: Water, alcohol foam, dry chemical, or carbon dioxide; Fire Extinguishing
Agents Not to be Used: Water or foam may cause frothing; Special Hazarcls of CombmOn Products:
Not pertinent; Behavior in Fire: Not pertinent; Ignition Temperature (deg. F): 580 (calc.); Electrical

Chemical Reactivity - Reactivity with Water : No reaction; Reactivity with Common Materials: No
reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Flush with
water; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.

Health Hazards Information - Recommended Personal Protective Equipment: Air-supplied mask;
plastic gloves; goggles; rubber apron; Symptoms Following Exposure: Inhalation of vapors causes
irritation, sometimes with nausea and vomiting; can also cause burns to the respiratory system.
Ingestion causes irritation of mouth and stomach. Vapor irritates eyes; liquid causes severe burn, like
caustic. Contact with skin causes irritation; General Treatment for Exposure: INHALATION: move
victim to fresh air and keep him quiet and comfortably warm; give oxygen if breathing is difficult; call
a physician. INGESTION: induce vomiting by giving a large volume of warm salt water; consult a
physician. EYES: immediately flush eyes with plenty of water for at least 15 min., then get medical
care. SKIN: flush with water; remove contaminated clothing and wash skin, if there is any redness or
evidence of burning; Toxicio by Inhalation (Threshold Limit Value): 5 ppm; Short-Tern Exposure
Limits: Mouse LCL,, 5,000 ppm for 20 min.; Toxicity by Ingestion: Grade 2; oral LDm 0.7 g/kg (rat);
