Experimental Properties:DECOMP TO CO2 & BENZYL CHLORIDE UPON HEATING AT 100-155 °C|DECOMP IN HOT ETHANOL & WATER|CONVERSION FACTORS: 6.96 MG/CU M= 1 PPM|Reacts with water to form hydrochloric acid|Flash point: 80.0 °C (Tag open cup), 107.9 °C (Tag closed cup)
Air and Water Reactions:Decomposes in moist air. Decomposes slowly in water to give corrosive hydrochloric acid and organic acids.
Reactive Group:Acyl Halides, Sulfonyl Halides, and Chloroformates
Reactivity Alerts:Water-Reactive
Reactivity Profile:BENZYL CHLOROFORMATE 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].
