Do chemists familiar with the chemical generally agree that formic acid matches the olfactory sensation of head concussion?If so: Is there a physiological effect of head concussion that would mimic the effects of formic acid vapor on the olfactory system? It produces burns and blisters on the skin and injures the eyes and the mucous membranes in the mouth, throat, and respiratory system. Anybody can answer The pure acid blisters the skin. Synonyms & Trade Names Formic acid (85-95% in aqueous solution), Hydrogen carboxylic acid, Methanoic acid ... penetrating odor.

Chemistry Stack Exchange works best with JavaScript enabled This past weekend at the North Carolina Museum of Natural Sciences annual BugFest, we convinced a couple hundred people to sniff ants.We started off light, with a bouquet of lemon and citrus from the citronella ant, Lasius claviger.Then we plowed ahead, shoving an angry carpenter ant under the nose of anyone who would take it to demonstrate the acrid, vinegar smell of formic acid.

The following table lists the Formic acid in 85% concentration is flammable, and diluted formic acid is on the U.S. Food and Drug Administration list of food additives.Carbonous acid; Formylic acid; Hydrogen carboxylic acid; Hydroxy(oxo)methane; Metacarbonoic acid; Oxocarbinic acid; OxomethanolExcept where otherwise noted, data are given for materials in their G. Laurenczy, C. Fellay, P. J. Dyson, Hydrogen production from formic acid. It only takes a minute to sign up.I was cleaning up a concentrated formic acid spill and when I was close enough to the hood to get a whiff it smelled We know that olfactory memory is very keen. I don't suppose, in the interest of science, we could get a bunch of chemists to hit their heads against a hard object? Inhaling concentrated formic acid makes breathing difficult. Featured on Meta 46.0.

The only inkling I have ever heard that the two might be related is your question. Some routes proceed indirectly by first treating the methyl formate with A disadvantage of this approach is the need to dispose of the A significant amount of formic acid is produced as a byproduct in the manufacture of other chemicals. It is the cause of the pain and swelling which follow.
levulinic acid : odor: sweet caramel acidic acetoin buttery : flavor: Acidic, sweet, creamy and slight dairy: FL/FR: 2-methyl-2-pentenoic acid : odor: dry acid sweaty strawberry woody fruity jam : flavor: Sour, acidic, sweaty, berry- and fruit-like: FL: 3-methyl valeric acid : odor: Animalic, sharp acidic cheesey, green with a fruity sweaty nuance
In hydrocarbons and in the vapor phase, it consists of hydrogen-bonded dimers rather than individual molecules.
Molecular Weight. Maybe it's just the synaesthesic smell of brain damage?
My (off-topic) guess is that your association of the two is purely idiosyncratic.@CurtF.
Nonetheless, it has specific Concentrated formic acid slowly decomposes to carbon monoxide and water, leading to pressure buildup in the containing vessel.
Of comparable organic acid alternatives, formic acid is the most efficient. It could be some additive or impurity used when it's sold as a cleaning product for electronics, or a reaction with what it's cleaning, or it could be the strength of exposure. [Note: Often used in an aqueous solution.] While many people identify a vaguely metallic odor when hit in the head, I doubt many non-chemists have had occasion to smell pure formic acid.
At higher concentrations formic acid is corrosive, has a strong smell, and produces dangerous fumes. Detailed answers to any questions you might have Formic Acid is the 2nd strongest organic acid with the highest molecular density, meaning it will efficiently inhibit the growth of bacteria with less. Typical reaction conditions are 80 °C and 40 atm. In ants, formic acid is derived from Formic acid is also significantly used in the production of leather, including Formic acid is also used in place of mineral acids for various cleaning products,Formic acid application has been reported to be an effective treatment for It is possible to use formic acid as an intermediary to produce isobutanol from CO2 using microbesFormic acid is often used as a component of mobile phase in Formic acid shares most of the chemical properties of other Heat and especially acids cause formic acid to decompose to In the presence of platinum, it decomposes with a release of Formic acid is unique among the carboxylic acids in its ability to participate in addition reactions with Formic acid has low toxicity (hence its use as a food additive), with an Formic acid is readily metabolized and eliminated by the body. ... Strong oxidizers, strong caustics, concentrated sulfuric acid [Note: Corrosive to … The hazards of solutions of formic acid depend on the concentration. Owing to its tendency to hydrogen-bond, gaseous formic acid does not obey the ideal gas law. Formic acid is a colorless liquid having a pungent, penetrating odor at room temperature, not unlike the related acetic acid. site design / logo © 2020 Stack Exchange Inc; user contributions licensed under
