In the 17th century, it was found in ants and decided to be called formic. insects excrete when bitten.
John Rayem, who discovered the compound, studied red ants. With their help I obtained the reagent.
Later, it turned out that formic acid not at all antlike, or rather, not only.
The substance is found in fruits, plants, human sweat, and urine. In addition to ants, bees also produce stings.
So, everyone will remember the feeling of getting into it. It's a burning sensation. Although the reagent is not considered strong, it is still.
The class name is justified. All its compounds taste sour. But now we are not talking about the general properties, but the characteristics of the ant reagent.
Properties of formic acid
HCOOH is formic acid formula. COOH is called a carboxyl group by chemists.
In the heroine she is alone, therefore, the connection is monobasic. CH 4 – methane. Accordingly, methane.
Putting the data together, we get a monobasic carbonic methane compound. It is biogenic because it is produced by living organisms, and not just synthesized.
The chain of molecules is open. If it reacts with alcohol, an esterified form of the compound will be obtained.
This is typical for oils, waxes, in general, vegetable and fats. Therefore, methane is called fatty.
However, in its series the compound stands apart, since the carboxyl group is attached to.
Usually, it comes into contact with an alkyl, that is, a hydrocarbon radical. As a result, the heroine of the article can be classified not only as fatty acids, but also as aldehydes, and simply as alcohols.
Like them, formic acid is capable of oxidizing. The result of the reaction is acid.
From aldehydes, the compound also acquired the ability to reduce mercury oxides. Formic acid reactions go with them when heated.
The result is nitrous oxide, and sometimes its metallic form. A similar reaction occurs with.
Interaction gives formic acid salt. It simply decomposes, again yielding pure argentum.
Antweed does not have a crystalline state. The compound is initially liquid and easily mixed with acetone, glycerin, and benzene.
The latter substances are aromatic. Formic acid also has an odor. The aroma is specific, sharp.
In aqueous solutions of the compound, it dissipates as the acid concentration decreases. The smell is pungent only in its anhydrous form.
Although, water may be found in it. You just need to mix sulfuric acid with formic acid. The result of the reaction is carbon monoxide and water.
The latter is used for household needs. But carbon monoxide is a product needed to create synthetic liquid fuels, organic acids, and alcohols.
Carbon dioxide can also be obtained from formic acid. The heroine of the article disintegrates into it and hydrogen in the presence of two metals - and.
One of them is enough for a reaction. In simple terms, carbon dioxide is carbon monoxide.
However, industrialists also need it. The compound is added to sodas, and.
It remains to find out why you need it yourself formic acid. Reviews industrialists, and not only, further.
Applications of formic acid
Application The compound was found in the food industry. If you see E236 on the package, you know this formic acid. Buy They offer drinks with it, both non-alcoholic and alcoholic, for example, wine.
E236 is also added to animal feed and canned vegetables. Accordingly, the additive helps products last longer. Conclusion: - the reagent has antibacterial properties.
In organism formic acid solution does not linger, is quickly removed. The main thing is not to overdo it.
If the compound concentrate accidentally gets on the skin or inside, burns, poisoning, and loss of vision cannot be avoided.
Animals are also offered products with formic acid. It's no longer about pets and their food.
Ant compounds are also added to hay and silage for livestock. Acid slows down the decay process. The decomposition of hay slows down, it remains healthy and tasty until spring.
Formic acid in pharmacies It is sold not only as a disinfectant, but also as a medicine for varicose veins.
Getting into small quantities, the reagent promotes vasodilation, and therefore improves blood flow.
This serves to prevent blood clots, a deadly consequence of varicose veins.
Blood stagnates in the veins, and clots form that attach to the walls of the vessels. Breaking away, they rush to the heart.
If they reach it, instant death will follow. The problem, as you can see, is acute and no less “acute” can help solve it. agent – formic acid.
Doctors also use methanoic acid as an immunostimulant. The compound plays this role in the treatment of tuberculosis.
The reagent is also capable of fighting fungal diseases. Although, some of the pharmaceutical products are more cosmetic-oriented.
So, based on the heroine of the article, acne remedies are made. You can also buy cream with formic acid.
It is usually taken for solariums. The product is slightly irritating and therefore warms the skin.
As a result, metabolic processes proceed faster, and the skin seems to attract ultraviolet radiation.
So, formic acid for tanning allows you to reduce the time you spend in the solarium, while still getting the desired effect.
In the chemical industry, formic acid serves as a reducing agent. Properties borrowed from aldehydes help.
The reagent is also needed in the textile industry for dyeing fabrics. Formic acid acts as a mordant.
It is needed to prepare the surface of the material, otherwise the dye will lie unevenly.
Interestingly, formic acid is also used outside of human society.
So, after hibernation, bears go to anthills and lie down on them. Giants bear no grudge against insects.
Formic acid extraction
Preparation of formic acid- a road that branches. There are several ways to obtain the reagent.
First - formic acid production from carbon compounds, for example, chloroform. It is exposed to diluted alkali.
It is also possible to saponify hydrocyanic acid, react with carbon dioxide on hydrite, and heat oxalic acid in the presence of glycerin.
However, industrialists use only one method. This is the passage of carbon monoxide through caustic soda.
An aqueous solution of the reagent can be obtained by distilling formic acid and sulfuric acid.
If you need to remove water, use oxalic acid concentrate. The usual fractional distillation of aqueous solutions will not help.
At 107 degrees, a mixture of methane acid and water is a constantly boiling composition. Moreover, the heroine of the article is only 77%.
Formic acid price
On formic acid price depends mainly on concentration. Most often, they sell solutions rather than a dehydrated reagent.
For medical purposes, for example, a concentration of only 1.4% is needed. The drug is called formic alcohol and costs about 20 rubles for a 50-ml bottle.
If additional components are added to the compound, for example, body care, the price will be different. So, a 75-ml bottle of skin balm can cost 110, or even 200 rubles.
For industrialists, the reagent is shipped in tanks or canisters of 25 and 35 kilograms. For the latter, they ask for around 3000-4000 rubles.
The price per kilo is 50-150 rubles. These are seller requests for 85 percent acid.
The price range is related to the purity of the connection and the personal ambitions of businessmen, as well as the place of production.
The most profitable products are from and domestic samples. The price is partly affected by packaging. It can be metal or plastic.
The presence of a convenient drain, like canisters, is taken into account. As a rule, this is not the case in barrels. There are a number of containers that, once opened, cannot be closed.
For this inconvenience, the price is slightly reduced. They also reduce it for wholesalers. For large orders you can save from 5 to 20, and sometimes even 25%.
The attitude towards regular partners is especially loyal. To some of them, acid is shipped even without prepayment.
In 1670, the English botanist and zoologist John Ray (1627-1705) conducted an unusual experiment. He placed red forest ants in a vessel, poured in water, heated it to a boil and passed a stream of hot steam through the vessel. This process is called steam distillation by chemists and is widely used to isolate and purify many organic compounds. After the steam condensed, Rey obtained an aqueous solution of a new chemical compound. It exhibited, and therefore was called formic acid (the modern name is methane). The names of salts and esters of methane acid - formates - are also associated with ants (Latin formica - “ant”).
Subsequently, entomologists - insect specialists (from the Greek “entokon” - “insect” and “logos” - “teaching”, “word”) determined that females and working ants have poisonous glands in their abdomens that produce acid. The forest ant has approximately 5 mg. Acid serves as an insect weapon for defense and attack. There is hardly a person who has not experienced their bites. The sensation is very reminiscent of a nettle burn, because formic acid is also contained in the finest hairs of this plant. Sticking into the skin, they break off, and their contents burn painfully.
Formic acid is also found in bee venom, pine needles, silkworm caterpillars, and in small quantities it is found in various fruits, organs, tissues, and animal and human secretions. In the 19th century formic acid (in the form of sodium salt) was obtained artificially by the action of carbon monoxide (II) on moisture at an elevated temperature: NaOH + CO = HCOONa. Conversely, under the influence of concentrated formic acid, it decomposes with the release of gas: HCOOH = CO + H 2 O. This reaction is used in the laboratory to obtain pure. When the sodium salt of formic acid - sodium formate - is strongly heated, a completely different reaction occurs: the carbon atoms of two acid molecules seem to be cross-linked and sodium oxalate is formed - a salt of oxalic acid: 2HCOONa = NaOOC-COONa + H 2.
An important difference between formic acid and others is that it, like a two-faced Janus, has both the properties of both an acid and a a carbon atom that is part of the aldehyde group H-CO-. Therefore, formic acid reduces silver from its solutions - it gives a “silver mirror” reaction, which is characteristic of aldehydes, but not characteristic of acids. In the case of formic acid, this reaction, which is also unusual, is accompanied by the release of carbon dioxide as a result of the oxidation of organic acid (formic) to inorganic acid (carbonic), which is unstable and decomposes: HCOOH + [O] = HO-CO-OH = CO 2 + H 2 O.
Formic acid is the simplest and at the same time the strongest carboxylic acid; it is ten times stronger than acetic acid. When the German chemist Justus Liebig first obtained anhydrous formic acid, it turned out that this was a very dangerous compound. When it comes into contact with the skin, it not only burns, but also literally dissolves it, leaving wounds that are difficult to heal. As Liebig's collaborator Karl Vogt (1817-1895) recalled, he had a scar on his hand for the rest of his life - the result of an “experiment” conducted jointly with Liebig. And it is not surprising - it was later discovered that anhydrous formic acid even dissolves nylon, nylon and other polymers that do not take diluted solutions of other acids and alkalis.
Formic acid found an unexpected application in the production of so-called heavy liquids - aqueous solutions in which even stones do not sink. Geologists need such liquids to separate minerals by density. By dissolving the metal in a 90% solution of formic acid, thallium formate HCOOTl is obtained. This solid salt may not hold a record for density, but it is distinguished by exceptionally high solubility: 0.5 kg (!) of thallium formate can be dissolved in 100 g of water at room temperature. For a saturated aqueous solution, the density varies from 3.40 g/cm 3 (at 20 o C) to 4.76 g/cm 3 (at 90 o C). The solution of a mixture of thallium formate and thallium malonate, the salt of malonic acid CH 2 (COOTl) 2, has an even greater density.
When these are dissolved (in a 1:1 ratio by weight) in a minimum amount of water, a liquid with a unique density is formed: 4.324 g/cm 3 at 20 o C, and at 95 o C the density of the solution can be increased to 5.0 g/cm 3 . Barite (heavy spar), quartz, corundum, malachite and even granite float in such a solution!
Formic acid has strong bactericidal properties. Therefore, its aqueous solutions are used as a food preservative, and in pairs they disinfect food containers (including wine barrels) and destroy bee mites. A weak aqueous-alcohol solution of formic acid (formic alcohol) is used in medicine for rubbing.
Due to its beneficial properties, formic acid is one of the most popular chemicals today. This universal product is used in various industries.
Salts of formic acid obtained by the reaction of carbonates, oxides and hydroxides of metals with acid are called formates. The most widely used are potassium, calcium and sodium formates.
Potassium formate
The potassium salt of formic acid is obtained by saponification of formamide. In our country it is allowed to be added to alcoholic beverages and food products as a preservative and salt substitute. It has an antimicrobial effect in an acidic environment, so it was previously used in canning using marinades. But recently it has been replaced by safer substances. Also applicable:
- in the production of cosmetics;
- as a tanning agent in tanning;
- as a coolant in refrigeration units;
- as an anti-frost additive in concrete;
- as part of drilling fluids.
Calcium formate
Calcium salt is obtained by reacting formic acid with calcium or its oxide. When working with it, it is necessary to take appropriate precautions, since the substance belongs to the third hazard class. In the Russian Federation it is allowed to be used instead of salt in dietary products and as a preservative for adding to soft drinks in limited quantities. For the production of cosmetics, special bioadditives based on it are often used. In addition, the following applies:
- for tanning leather;
- when dyeing fabrics;
- for printing colored wallpaper;
- for rapid hardening of building mixtures.
Sodium formate
Sodium formic acid is a by-product of the production of pentaerythritol. Used in three ways:
- in the food industry;
- in construction;
- in public utilities.
Preservative E237
This name is accepted for sodium formate in the international system of classification of food additives. Use as a preservative is due to its pronounced antimicrobial properties. Until recently, this food additive was widespread throughout the world, but due to the negative impact on the human body due to overuse, it was banned in many countries. Our country has established clear rules to limit the use of the E237 additive in food products. And to ensure the safety of workers at industrial enterprises, they are prescribed special clothing that insulates the surface of the body and respiratory organs from contact with a substance belonging to hazard class 4.
Antifreeze additive
In order for concrete mixtures to be used in winter construction, care must be taken to ensure that they do not harden in the cold. Sodium formate slows down the freezing process of water in the solution. To avoid the appearance of internal stress caused by the use of an anti-freeze additive, its dosage and method of application are selected in strict accordance with the technology.
Road cleaning
In recent years, formates have been used to remove snow and ice from roads. Regular salt is corrosive and has a negative impact on the environment. Sodium formate is less corrosive and provides reliable protection against snow and ice without negative effects. Its use allows not only to remove ice, but also to prevent the new formation of ice cover. Therefore, municipal services are increasingly using it as a harmless and effective deicer.

Ants bring many benefits to nature. They destroy pests, enrich the soil with potassium and fluorine, and loosen the soil. Therefore, one found in the forest cannot be touched. But garden individuals become enemies of the harvest. Insects acidify the soil too much and... Many people use salt to kill ants in their gardens and apartments. It helps destroy pests quickly and without unnecessary chemicals.
How to use in an apartment
It is not always possible to use it in a closed space. They can be swallowed by a curious baby or pet. And adults are at risk when they use poison. In this case, salt helps. It quickly removes ants from any part of the house.
On a note!
It is better to use regular table salt. It's inexpensive and helps a lot.
To force ants to leave human habitation, the garden should use the following recipes:
- Sprinkle fine salt into cracks, window sills and doors.
- Mix salt and salt in equal proportions. Treat ant paths with the mixture.
- Mix the substance with hot pepper. Fall asleep in places where pests accumulate.
The insects prefer to move to a safer place and leave the human home.
How to use in the garden
They cause the most problems. But even here ordinary salt can cope with them.
I don’t touch the ants in the forest, but kill them in the garden with salt. I once read that boiling water helps get rid of them. Regular boiling water didn’t help me, but salty water did. I'm waiting for evening to come and the insects to go to their nest. Then I prepare a strong saline solution, bring it to a boil and pour it on the pests. But this method is not suitable for trees. It helps to wrap the barrel with polyethylene, covered with .
Tamara Lvovna, Moscow
Salt against ants in the garden is used as follows:
- A thin trail of sweet water flows from the anthill. When the ants begin to run towards, they are sprinkled with the product or trampled under foot. The next day the procedure is repeated.
- Hot salt water is poured into a spray bottle and sprayed onto the pests.
- The ant nest is filled with table salt.
If you can’t kill insects using these methods, then it’s worth a try.
