Formic acid is a toxic substance contained in ant venom and is used for self defense or for attacking rivals. [13][14], Formic acid can also be obtained by aqueous catalytic partial oxidation of wet biomass by the OxFA process. The acid is a powerful insecticide which rids its plumage of parasites. formic synonyms, formic pronunciation, formic translation, English dictionary definition of formic. Beekeepers use formic acid as a miticide against the tracheal mite (Acarapis woodi) and the Varroa destructor mite and Varroa jacobsoni mite. [15][16] A Keggin-type polyoxometalate (H5PV2Mo10O40) is used as the homogeneous catalyst to convert sugars, wood, waste paper, or cyanobacteria to formic acid and CO2 as the sole byproduct. [25], A major use of formic acid is as a preservative and antibacterial agent in livestock feed. No form of life is so richly provided with formic acid as the small red ant, that builds huge mounds of sand. [citation needed], Formic acid is unique among the carboxylic acids in its ability to participate in addition reactions with alkenes. The following table lists the EU classification of formic acid solutions: Formic acid in 85% concentration is flammable, and diluted formic acid is on the U.S. Food and Drug Administration list of food additives. Yields of up to 53% formic acid can be achieved. Formic acid is an irritating chemical present in the sprayed venom of some ant species and in the secretion released from some stinging nettles. [12] It is commercially available in solutions of various concentrations between 85 and 99 w/w %. Concentrated sulfuric acid dehydrates formic acid to carbon monoxide. Formic acid was long considered a chemical compound of only minor interest in the chemical industry. Carpenter ants also spray a defensive chemical of formic acid, which they can spray into the bite wound, further increasing the pain. It is produced in a special gland in the abdomen of numerous species of ant. Because of its high acidity, solutions in alcohols form esters spontaneously. [29], Formic acid application has been reported to be an effective treatment for warts. [6][7] Owing to its tendency to hydrogen-bond, gaseous formic acid does not obey the ideal gas law. [20] The formate could be used as feed to modified E. coli bacteria for producing biomass. Some species, including carpenter ants, spray formic acid, a caustic chemical that smells a lot like vinegar, when they feel threatened. Omissions? [17] Glycerol acts as a catalyst, as the reaction proceeds through a glyceryl oxalate intermediate. In fact, formic acid was first distilled from ants by chemists (or … [31][32], It is possible to use formic acid as an intermediary to produce isobutanol from CO2 using microbes[33][34][35], Formic acid is often used as a component of mobile phase in reversed-phase high-performance liquid chromatography (RP-HPLC) analysis and separation techniques for the separation of hydrophobic macromolecules, such as peptides, proteins and more complex structures including intact viruses. This group of ants does not sting, but it can bite using strong mouth parts. These types of ants also spray formic acid from the tips of their abdomens at … Preparation.—Formic acid derived its name from the fact that it was obtained by distillation of red ants (Formica rufa, Linné). It now finds increasing use as a preservative and antibacterial in livestock feed. [11], In 2009, the worldwide capacity for producing formic acid was 720 thousand tonnes (1.6 billion pounds) per year, roughly equally divided between Europe (350 thousand tonnes or 770 million pounds, mainly in Germany) and Asia (370 thousand tonnes or 820 million pounds, mainly in China) while production was below 1 thousand tonnes or 2.2 million pounds per year in all other continents. It impacts their stomachs, their nervous systems, and their exoskeletons. Of or relating to ants. Although using formic acid as an antidote hadn’t been observed before, ants and formic acid have a long history together. In … Formic acid was first isolated from certain ants and was named after the Latin formica, meaning “ant.” It is made by the action of sulfuric acid upon sodium formate, which is produced from carbon monoxide and sodium hydroxide. The methyl and ethyl esters of formic acid are commercially produced. [49] Another possible effect of chronic exposure is development of a skin allergy that manifests upon re-exposure to the chemical. Define formic. Without treatment, blindness results. The angry ants discharge a shower of formic acid. Liquid formic acid tends to supercool. Formic acid is one of the simplest organic acids. Some formate esters are artificial flavorings and perfumes. [23] The conjugate base of formic acid, formate, also occurs widely in nature. Formicine ants have a single node-like or scale-like petiole (postpetiole entirely lacking) and the apex of the abdomen has a circular or U-shaped opening (the acidopore), usually fringed with hairs. It is also found in the trichomes of stinging nettle (Urtica dioica).
