化学的性質
化学的特性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).

Environmental Fate
TERRESTRIAL FATE: Dichloroacetyl chloride hydrolyzes on contact with water(1); therefore, hydrolysis is expected to be the only important environmental fate process in moist soils. Based on a vapor pressure of 25.3 mm Hg at 25 degC(2), dichloroacetyl chloride is expected to evaporate relatively rapidly from dry surfaces. (SRC)
AQUATIC FATE: Dichloroacetyl chloride hydrolyzes on contact with water(1); therefore, hydrolyses is expected to be the only important environmental fate process in water. The hydrolysis products are expected to be HCl and dichloroacetic acid. (SRC)
ATMOSPHERIC FATE: When released to the atmosphere, vapor phase dichloroacetyl chloride is expected to react with photochemically produced hydroxyl radicals at a theoretically estimated half-life rate of 22.8 days(1). The tropospheric gas-phase hydrolysis reaction between dichloroacetyl chloride and water has a half-life in excess of 100 years(2). Atmospheric wash-out and transformation via rain may be possible. (SRC)
Adverse EffectsDermatotoxin - Skin burns.
Exposure RoutesThe substance can be absorbed into the body by inhalation, through the skin and by ingestion.
Signs and Symptoms
Sore throat. Cough. Burning sensation. Shortness of breath. Laboured breathing. Symptoms may be delayed.
Pain. Redness. Blisters. Skin burns.
Pain. Redness. Severe deep burns. Loss of vision.
Burning sensation. Abdominal cramps. Shock or collapse.
ICSC Environmental DataThis substance may be hazardous to the environment. Special attention should be given to water quality.
Soil Adsorption/Mobility
Dichloroacetyl chloride hydrolyzes on contact with water(1), therefore, leaching in moist soils will not occur as the compound will be chemically transformed. The hydrolysis product, dichloroacetic acid, should be susceptible to leaching. (SRC)
Natural Pollution SourcesDichloroacetyl chloride is not known to occur naturally. (SRC)
Human Toxicity Excerpts
...STRONG IRRITANT TO SKIN & EYES.
SYMPTOMATOLOGY (...INGESTION OR SKIN CONTACT): 1. CORROSION OF MUCOUS MEMBRANES OF MOUTH, THROAT AND ESOPHAGUS, WITH IMMEDIATE PAIN AND DYSPHAGIA. NECROTIC AREAS...GRAYISH WHITE BUT SOON ACQUIRE A BLACKISH DISCOLORATION (YELLOW IN CASE OF NITRIC ACID) & SOMETIMES SHRUNKEN OR WRINKLED TEXTURE... 2. EPIGASTRIC PAIN...MAY BE ASSOC WITH NAUSEA & VOMITING... AT TIMES, GASTRIC HEMORRHAGE MAY BE INTENSE, AND VOMITUS THEN CONTAINS FRESH BLOOD. PROFOUND THIRST. 3. ULCERATION OF ALL MEMBRANES AND TISSUES WITH WHICH THE ACID COMES IN CONTACT. AFTER THE INGESTION OF CONCN MINERAL ACID, THIS CORROSION MAY LEAD WITHIN A FEW HR OR A FEW DAYS TO GASTRIC PERFORATION AND PERITONITIS. 4. CIRCULATORY COLLAPSE WITH CLAMMY SKIN, WEAK & RAPID PULSE, SHALLOW RESP, AND SCANTY URINE. CIRCULATORY SHOCK IS OFTEN IMMEDIATE CAUSE OF DEATH. /ACIDS/
Artificial Pollution Sources
Fugitive atmospheric emissions resulting from industrial production and use operations are a potential source of dichloroacteyl chloride release to the environment(SRC). Dichloroacetyl chloride can be formed in the atmosphere by the atmospheric oxidation of trichloroethylene(1).
Environmental BioconcentrationDichloroacetyl chloride hydrolyzes on contact with water(1), therefore, bioconcentration in aquatic organisms is not possible. (SRC)
Volatilization from Water/Soil
Dichloroacetyl chloride hydrolyzes on contact with water(1); therefore, volatilization from water or wet soils will not occur(SRC). With a vapor pressure of 25.3 mm Hg at 25 degC(2), dichloroacetyl chloride is expected to evaporate relatively rapidly from dry surfaces(SRC).
Non-Human Toxicity Excerpts
RATED 10 ON RABBIT EYES. ...TESTED EXTERNALLY ON EYES OF RABBITS &...RATED NUMERICALLY ON SCALE OF 1-10 ACCORDING TO DEGREE OF INJURY...AFTER 24 HR /OBSERVATION/, PAYING PARTICULAR ATTENTION TO CONDITION OF CORNEA. MOST SEVERE INJURIES HAVE BEEN RATED 10.
Dichloroacetyl chloride (1 and 5% LD50 for 4 wk) is not toxic to liver of rats of both sexes, as shown by histochem studies.
