BENZYL CHLOROFORlMATE
Chemical Designations - Synonym: Carbobenzoxy Chloride; Chloroformic Acid, Benzyl Ester;
Benzylcarbonyl Chloride; Benzyl Chlorocarbonate; Chemical Formula: C,H,CI&OCOCl.
Observable Characteristics - Physical State (as nomlly shipped) : Liquid; Color: Colorless; Odor:
Irritating; sharp, penetrating.
Physical and Chemical Properties - Physical State at I5 “c and I ai%. : Liquid; Molecular Weight:
170.6; Boiling Point at I am.: 306, 152, 425; Freezing Point: Not pertinent; Critical Temperature:
Not pertinent; cn‘tical Pressure: Not pertinent; Speczfic Gravity: 1.22 at 20°C; Vapor (Gas) Density:
Not pertinent; Ratio of Speczfic Heats of Vapor (Gas): Not pertinent; Ldent Heat of Vaporization: 90,
50, 2.1; Heat of Combustion: -10,000, -5,700, -240; Heat ofDecomposition: Not pertinent.
Health Hazards Information - Reconunended Personal Protective Equipment: Self-contained breathing
apparatus or acid-type canister mask; goggles or face shield; rubber gloves; protective clothing;
Symptom Following Exposure: Inhalation causes mucous membrane irritation. Eyes are irritated by
excessive exposure to vapor. Liquid causes severe irritation of eyes and irritates skin. Ingestion causes
irritation of mouth and stomach; General Treatment for Exposure: INHALATION: remove from
exposure, support respiration, call physician. EYES: irrigate withcopious amounts of water for 15 min.
SKIN: flush with large quantities of water; wash with soap and water. INGESTION: give large
amounts of water, do NOT induce vomiting; Toxicity by Inhdation (Threshold Limit Value): Data not
available; Short-Term Exposure Limits: Data not available; Toxicity by Ingestion: Grade 3; LD, to 500
mglkg; Late Toxicity: Data not available; Vapor (Gas) Im’tant Characteristics: Vapors cause moderate
irritation such that personnel will find high concentrations unpleasant. The effect is temporary; Liquid
or Solid Imht Characteristics: Causes smarting of the skin and first-degree burns on short exposure
and may cause second-degree on long exposure; Odor Threshold Data not available.
Fire Hazards - Flash Point (deg. F): 176 OC, 227 CC; Vigorous decomposition occurs at these
temperatures. These values are anomalous due to the effect of the decomposition products of benzyl
chloride and CO,; Flammable Limits in Air (96): Not pertinent; Fire Extinguishing Agents: Dry
chemical, foam, carbon dioxide; Fire Extinguishing Agents Not To Be Used No data; Special Hazards
of Combustion Products: Toxic phosgene, hydrogen chloride, and benzyl chloride vapors may form;
Behavior in Fire: Containers may explode; Ignition Temperature: No data; Electrical Hazard No data;
Burning Rate: 4.0 mm/min.
Chemical Reactivity - Reactivity with Water: Forms hydrogen chloride (hydrochloric acid). Reaction
not very vigorous in cold water; Reactivity with Common Materials: Slow corrosion of metals; Stability
During Transport: Stable; Neutmlizing Agents for Acids and Caustics: Flush with and rinse with sodium
bicarbonate or lime solution; Polymerization: Not pertinent; Inhibitor of Polymerim’on: Not pertinent.

pertinent; Critical Pressure: Not pertinent; @.mijic Gravity: 1.90 at 25°C; Vapor (Gas) Density: Not
pertinent; Ratio of Specific Heats of Vapor (Gus): Not pertinent; Ueru Heat of Vaporization: Not
pertinent; Heat of Combustion: Not pertinent; Heat ofDecomposition: Not pertinent.
Health Hazards Information - Recommended Personal Protective Equipment: Respiratory protection;
gloves; freshly laundered clothing; chemical safety goggles; Symptoms Following Exposure: Inhalation
causes pneumonitis, nasopharyngitis, tracheobronchitis, dyspnea, chromic cough. Ingestion causes
irritation of mouth and stomach. Contact with dust causes conjunctival inflamation of eyes and irritation
of skin. Any dramatic, unexplained weigh loss should be considered as a possible first indication of
beryllium disease; Geneml Treafment for Exposure: INHALATION: chest x-ray should be taken
immediately for evidence of pneumonitis. EYES: flush with water for at least 15 min; if irritation
persists, get medical attention. SKIN: cuts or puncture wounds in which beryllium may be embedded
