Experimental Properties:Vigorously decomposed and dissolved by water or alcohol|Vigorously reacts with water to form propionic acid and hydrochloric acid. Based on a scenario where the chemical is spilled into an excess of water (at least 5 fold excess of water), half of the maximum theoretical yield of hydrogen chloride gas will be created in 0.09 minutes.|Hydroxyl radical reaction rate constant = 5.9X10-13 cu cm/molec-sec at 25 °C (est)
Air and Water Reactions:Highly flammable. Vigorously reacts with water to form propionic acid and hydrochloric acid [Merck 11th ed. 1989]. Based on a scenario where the chemical is spilled into an excess of water (at least 5 fold excess of water), half of the maximum theoretical yield of Hydrogen Chloride gas will be created in 0.09 minutes. Experimental details are in the following: "Development of the Table of Initial Isolation and Protective Distances for the 2008 Emergency Response Guidebook", ANL/DIS-09-2, D.F. Brown, H.M. Hartmann, W.A. Freeman, and W.D. Haney, Argonne National Laboratory, Argonne, Illinois, June 2009.
Reactive Group:Acyl Halides, Sulfonyl Halides, and Chloroformates
Reactivity Alerts:Highly Flammable
Reactivity Profile:Acid halides, such as PROPIONYL CHLORIDE, are water reactive; some are violently reactive. They are incompatible with strong oxidizing agents, alcohols, amines, and alkali. 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].
Corrosivity:Corrosive
