Esters, salts, and the anion derived from formic acid are called formates.

    Formic acid, although not widely used as a solvent, is of interest as an example of a protic solvent with high acidity. © 2018 by the U.S. Secretary of Commerce [48] Some chronic effects of formic acid exposure have been documented. Questions? in front of the letter e.g.

    Some routes proceed indirectly by first treating the methyl formate with ammonia to give formamide, which is then hydrolyzed with sulfuric acid: A disadvantage of this approach is the need to dispose of the ammonium sulfate byproduct.

    The net reaction is thus: Another illustrative method involves the reaction between lead formate and hydrogen sulfide, driven by the formation of lead sulfide.

In the laboratory, formic acid can be obtained by heating oxalic acid in glycerol and extraction by steam distillation. [6] As of 2009[update], the largest producers are BASF, Eastman Chemical Company, LC Industrial, and Feicheng Acid Chemicals, with the largest production facilities in Ludwigshafen (200 thousand tonnes or 440 million pounds per year, BASF, Germany), Oulu (105 thousand tonnes or 230 million pounds, Eastman, Finland), Nakhon Pathom (n/a, LC Industrial), and Feicheng (100 thousand tonnes or 220 million pounds, Feicheng, China).

    In ants, formic acid is derived from serine through a 5,10-methenyltetrahydrofolate intermediate.

[24], In August 2020 researchers at Cambridge University announced a stand alone advanced ‘photosheet’ technology that converts sunlight, carbon dioxide and water into oxygen and formic acid with no other inputs. An assay for formic acid in body fluids, designed for determination of formate after methanol poisoning, is based on the reaction of formate with bacterial formate dehydrogenase. Formic acid, systematically named methanoic acid, is the simplest carboxylic acid, and has the chemical formula HCOOH. The U.S. OSHA Permissible Exposure Level (PEL) of formic acid vapor in the work environment is 5 parts per million parts of air (ppm). Copyright for NIST Standard Reference Data is governed by [citation needed], Heat and especially acids cause formic acid to decompose to carbon monoxide (CO) and water (dehydration). If the reaction mixture is heated to higher temperatures, allyl alcohol results. ; Yang, Z.C., Prediction of Retention Indexes I. Structure-Retention Index Relationship on Apolar Columns, J. a preservative and antibacterial agent in livestock feed. In Europe, it is applied on silage, including fresh hay, to promote the fermentation of lactic acid and to suppress the formation of butyric acid; it also allows fermentation to occur quickly, and at a lower temperature, reducing the loss of nutritional value. Formic acid ACS reagent, 88-91% CAS Number 64-18-6.

    Formula Weight. presented with a COA Request form. Use as a coagulant in the production of rubber[6] consumed 6% of the global production in 2009.[12]. Pure formic acid is a liquid with a flash point of +69 °C, much higher than that of gasoline (−40 °C) or ethanol (+13 °C).

    Formic acid is a colorless liquid having a pungent, penetrating odor[5] at room temperature, not unlike the related acetic acid.

    The simplest example of an ester, it is a colorless liquid with an ethereal odour, high vapor pressure, and low surface tension. [21][22] There exist natural microbes that can feed on formic acid or formate (see Methylotroph).

    It is a precursor to many other compounds of commercial interest.

The first person to describe the isolation of this substance (by the distillation of large numbers of ants) was the English naturalist John Ray, in 1671. The concentrated acid is corrosive to the skin.[6].
