ANTIMONY PENTAFLUORIDE 25

Observable Characteristics - Physical State (as nomzally shipped): Liquid; Color: Colorless to
medium brown; yellow; red-brown; Odor: Pungent; offensive.
Physical and Chemical Properties - Physical State at I5 “c and I atm. : Liquid; Molecular Weight:
299.05; Boiling Point at I atm.: 347, 175,448; Freezing Point: 37, 3,276; Critical Temperature: Not
pertinent; Critical Pressure: Not pertinent; Specipc Gravity: 2.354 at 20°C (liquid); Vapor (Gas)
Density: Not pertinent; Ratio of Specific Heats of Vapor (Gas): Not pertinent; Latent Heat of
Vaporization: 68.9, 38.3, 1.60; Heat of Combustion: Not pertinent; Heat of Decomposition: Not
pertinent.
Health EIazards Information - Recommended Personal Protective Equipment: Organic vapor-acid gas
type canister mask; rubber, neoprene, vinyl, etc. gloves; chemical safety goggles, plus face shield
where appropriate; acid resistant clothing, plus apron for splash protection; rubber safety shoes or
boots; hard hat; Symptoms Following Exposure: Inhalation causes irritation of nose and throat. Contact
of liquid with eyes or skin causes severe burns. Ingestion causes vomiting and severe burns of mouth
and stomach. Overexposure by any route can cause bloody stools, slow pulse, low blood pressure,
coma, convulsions, cardiac arrest; General Treatment for Exposure: INHALATION: remove to clean
air; rinse mouth and gargle with water; if overexposure is serious, get prompt medical attention. EYES:
flush eyes and eye-lids thoroughly with large amounts of water; get prompt medical attention. SKIN:
flush thoroughly with water; remove contaminated clothing; wash affected area with soap and water;
if overexposure is serious, get prompt medical attention. INGESTION: dilute by drinking water; if
vomiting occurs, administer more water. If overexposure is serious, get prompt medical attention;
Toxicity by Inhalation (Threshold Limit Value): 0.5 mg/m3 as antimony; Short-Tern Exposure Limits:
Data not available; Toxicity by Ingestion: Grade 2; oral LD50 1,115 mg/kg (rat), 900 mg/kg (guinea
pig); Late Tmicity: Antimony poisoning may result; Vapor (Gas) Irritant Characteristics: Vapors are
moderately irritating such that personnel will not usually tolerate moderate or high vapor
concentrations; Liquid or Solid Irritant Characteristics: Severe skin irritant; causes second- and third-
degree burns on short contact and is very injurious to the eyes; Odor 77zreshold Data not available.
Fire Hazards - Flash Point: Not flammable; Flammable Limits in Air (56): Not flammable; Fire
Extinguishing Agents: Not pertinent; Fire Extinguishing Agents Not To Be Used Do not use water or
foam on adjacent fires; Special Hazards of Combustion Products: Not pertinent; Behavior in Fire:
Irritating fumes of hydrogen chloride given off when water or foam is used to extinguish adjacent fire;
Ignition Temperature: Not pertinent; Electrical Hazard Not pertinent; Burning Rate: Not pertinent.
Chemical Reactivity - Reactivity with Water: Reacts to form hydrogen chloride gas (hydrochloric
acid); Reactivity with Common Materials: Causes corrosion on metal; Stability During Transport:
Stable; Neutralizing Agents for Acids and Caustics: Soda ash or soda ash-lime mixture; Polymerizah‘on:
Not pertinent; Inhibitor of Polymerization: Not pertinent.
