04 · Handling and storage
Storing and handling Dichloroacetyl chloride
Reactivity
Solutions of DICHLOROACETYL CHLORIDE in acetone are stable for less than two hours and fresh solution should be prepared before each use (NIP). 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].
