Hazard InformationBack Directory
[General Description]

A colorless liquid with an acrid odor. Vapors irritate eyes and mucous membranes. Corrosive to metals and tissue. Long-term inhalation of low concentrations or short-term inhalation of high concentrations can result in adverse health effects.
[Reactivity Profile]

BENZYL CHLOROFORMATE(501-53-1) decomposes slowly in water forming benzyl alcohol, HCl, and CO2. Gives off HCl fumes in moist air. Reacts with bases, both organic and inorganic. Attacks many metals especially in humid atmosphere [Handling Chemicals Safely 1980. p. 476]. Catalytic impurity incidents involving the iron catalyzed decomposition of benzoyl chloroformate have caused several explosions. The iron presumably comes from corrosion of steel storage tanks [Loss Prev. Bull., 1975, (003), 2]. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291].
[Air & Water Reactions]

Decomposes in moist air. Decomposes slowly in water to give corrosive hydrochloric acid and organic acids.
[Hazard]

Highly toxic, emits very toxic phosgene fumes at 100C. Irritant to eyes.
[Health Hazard]

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.
