Fluoroacetic acid Usage And Synthesis
  • Chemical PropertiesColorless crystal. Soluble in water and alcohol.
  • Chemical PropertiesFluoroacetic acid is a colorless crystalline solid.
  • UsesFluoroacetic acid (CH2FCOOH) is very poisonous. It is used to kill rats and mice.
  • UsesRodenticide.
  • DefinitionChEBI: A haloacetic acid that is acetic acid in which one of the methyl hydrogens is substituted by fluorine.
  • General DescriptionA colorless crystalline solid. May be toxic by ingestion. Used to make other chemicals.
  • Air & Water ReactionsWater soluble.
  • Reactivity ProfileFluoroacetic acid is a halogenated carboxylic acid derivative. Carboxylic acids donate hydrogen ions if a base is present to accept them. They react in this way with all bases, both organic (for example, the amines) and inorganic. Their reactions with bases, called "neutralizations", are accompanied by the evolution of substantial amounts of heat. Neutralization between an acid and a base produces water plus a salt. Carboxylic acids with six or fewer carbon atoms are freely or moderately soluble in water; those with more than six carbons are slightly soluble in water. Soluble carboxylic acid dissociate to an extent in water to yield hydrogen ions. The pH of solutions of carboxylic acids is therefore less than 7.0. Many insoluble carboxylic acids react rapidly with aqueous solutions containing a chemical base and dissolve as the neutralization generates a soluble salt. Carboxylic acids in aqueous solution and liquid or molten carboxylic acids can react with active metals to form gaseous hydrogen and a metal salt. Such reactions occur in principle for solid carboxylic acids as well, but are slow if the solid acid remains dry. Even "insoluble" carboxylic acids may absorb enough water from the air and dissolve sufficiently in Fluoroacetic acid to corrode or dissolve iron, steel, and aluminum parts and containers. Carboxylic acids, like other acids, react with cyanide salts to generate gaseous hydrogen cyanide. The reaction is slower for dry, solid carboxylic acids. Insoluble carboxylic acids react with solutions of cyanides to cause the release of gaseous hydrogen cyanide. Flammable and/or toxic gases and heat are generated by the reaction of carboxylic acids with diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides. Carboxylic acids, especially in aqueous solution, also react with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), to generate flammable and/or toxic gases and heat. Their reaction with carbonates and bicarbonates generates a harmless gas (carbon dioxide) but still heat. Like other organic compounds, carboxylic acids can be oxidized by strong oxidizing agents and reduced by strong reducing agents. These reactions generate heat. A wide variety of products is possible. Like other acids, carboxylic acids may initiate polymerization reactions; like other acids, they often catalyze (increase the rate of) chemical reactions.
  • HazardToxic by ingestion.
  • Health HazardFluoroacetic acid is very toxic; ingestion of small quantities may cause death.
  • Fire HazardWhen heated to decomposition, Fluoroacetic acid emits highly toxic fumes of fluorine containing compounds. Some of these materials may burn but none ignite readily. These materials may ignite combustibles (wood, paper, oil, etc.).
  • Safety ProfilePoison by ingestion, subcutaneous, intraperitoneal, and intravenous routes. Affects the human central nervous system, causing convulsions and ventricular fibrdlation. When heated to decomposition it emits toxic fumes of F and Na2O. See also SODIUM FLUOROACETATE.
  • Potential ExposureThis material is used as a rodenticide and a drug.
  • ShippingUN2642 Fluoroacetic acid, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
  • IncompatibilitiesIncompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explo sions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Reacts with reducing agents releasing flammable gas.
  • Waste DisposalUse a licensed professional waste disposal service to dispose of this material. Dissolve 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 regula tions must be observed.
