화학적 성질
Dichloroacetyl chloride (DCAC) is a colourless to light yellow fuming liquid with an acrid, penetrating odor. It is irritating to the eyes and mucous membranes (HSDB 2003b). DCAC is insoluble in water, but decomposes quickly to form HCl and dichloroacetic acid (t1/2 of hydrolysis of 0.0023 seconds in water at 25°C, and 0.2 seconds in 89.1:10.9 water-acetone at -20°C (Prager et al. 2001, Ugi and Beck 1961).

제조 및 합성 방법
제조 방법
Dichloroacetyl chloride can be synthesized by the reaction of dichloroacetic acid and chlorosulfonic acid. Or from the oxidation of trichloroethylene. Trichloroethylene and azobisisobutyronitrile (catalyst) were heated to 100°C, and oxygen was introduced to react under 0.6MPa pressure, maintaining the oil bath temperature at 110°C, and reacted for 10h, The product dichloroacetyl chloride is distilled off under normal pressure.
