Ethyl chloroacetate Usage And Synthesis
  • Chemical PropertiesEthyl chloroacetate is a colourless liquid with a pungent, fruity odor.Ethyl chloroacetate has a vapor pressure of 10mmHg at 38 °C (Lewis, 1997). It is insoluble in water, but miscible with alcohol, ether, and acetone (Lide, 1998); it is soluble in benzene (Lewis, 1997). Ethyl chloroacetate readily decomposes in hot water and alkalis (Lewis, 1997).
  • UsesReagent used in the preparation of 5 member heterocycles.
  • Synthesis Reference(s)Tetrahedron, 23, p. 359, 1967 DOI: 10.1016/S0040-4020(01)83321-4
  • General DescriptionA clear colorless liquid with a pungent odor. Flash point 100°F. Denser than water and insoluble in water. Vapors heavier than air.
  • Air & Water ReactionsHighly flammable. Slow hydrolysis to acidic products will cause slow corrosion of common metals. No hazard involved. [USCG, 1999].
  • Reactivity ProfileEthyl chloroacetate is a chlorinated ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.
  • HazardStrong irritant to eyes.
  • Health HazardInhalation causes irritation of mucous membrane, headache, and nausea. Contact with liquid causes extreme eye irritation and conjunctivitis; irritates skin if not removed at once. Ingestion causes irritation of mouth and stomach.
  • Fire HazardSpecial Hazards of Combustion Products: Irritating, toxic hydrogen chloride and phosgene may be generated in fires.
  • Chemical ReactivityReactivity with Water Very slow, not hazardous; Reactivity with Common Materials: Slow hydrolysis to acidic products; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
  • Safety Profileoison by skin contact and subcutaneous routes. A severe eye irritant. Questionable carcinogen with experimental neoplastigenic data.Flammable liquid; a dangerous fire hazard when exposed to heat or flame; can react vigorously with oxidizing materials. Will react with water or steam to produce toxic and corrosive fumes. Vigorous reaction with sodium cyanide. To fight fire, use water, foam, CO2, dry chemical. When heated to decomposition it emits highly toxic fumes of cl-.
  • Potential ExposureUsed to make rodenticides, dyes, and other chemicals. Also used as a military poison
  • ShippingUN1181 Ethylchloroacetate, Hazard class: 6.1; Labels: 6.1-Poisonous materials, 3-Flammable liquid.
  • Purification MethodsShake the ester with satutated aqueous Na2CO3 (three times), aqueous 50% CaCl2 (three times) and saturated aqueous NaCl (twice). Dry it with Na2SO4 or MgSO4 and distil it. [Beilstein 2 IV 481.] LACHRYMATORY.
  • IncompatibilitiesMay form explosive mixture with air. Incompatible with strong bases; strong acids; reducing agents. Moisture, water, and steam contact forms toxic and corrosive fumes. Violent reaction with oxidizers, alkaline earth metals (barium, calcium, magnesium, strontium, etc.), alkaline metals, sodium cyanide. Attacks metals in the presence of moisture.
  • Waste DisposalDissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal.
