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.
Formic acid (E 236, methanoic acid) is in first place among monobasic acids (saturated). Under normal conditions, the substance is a colorless liquid. The chemical formula of formic acid is HCOOH.
Along with its acidic characteristics, it also exhibits aldehyde qualities. This is due to the structure of the substance E236.
In nature, the substance is found in nettles, pine needles, fruits, caustic bees and secretions, and in ants. Formic acid was first discovered and described in the 17th century. The substance got its name because it was found in ants.
The chemical properties of a substance appear depending on the concentration. In accordance with the EU classification, with a quantitative composition of up to 10% it is irritating, and more than 10% is corrosive.
100% formic acid (liquid) causes very severe burns upon contact with skin. Contact of even a small amount of it in such a concentration on the skin causes severe pain. The affected area first begins to turn white, as if covered with frost, then becomes waxy. A red border forms around the burned area. Acid can quickly penetrate the fatty skin layer, so it is necessary to immediately rinse the affected area.
Concentrated vapors of the substance can cause damage to the respiratory tract and eyes. If accidentally ingested, even in diluted form, methanoic acid causes severe necrotic gastroenteritis.
The body quickly processes and eliminates the substance. However, at the same time, E236 and formaldehydes formed during the process provoke lesions that lead to blindness.
Salts of formic acid are called formates. Heating with concentrated water leads to the decomposition of E236 into H2O and CO, which is used to form carbon monoxide.
Formic acid is produced industrially from carbon monoxide.
Substances 100.7, freezing point - 8.25 degrees.
At room conditions, E236 decomposes into water. According to experimental evidence, methanoic acid is stronger than acetic acid. However, due to the ability of the former to rapidly decompose, it is used as a solvent extremely rarely.
It is believed that E236 is a very hygroscopic substance. During the experiments, it was found that obtaining an anhydrous drug using dehydrating reagents is not possible.
Contact of formic acid with moist air is unacceptable.
E236 with a purity of more than 99% can be obtained from an aqueous solution using two-stage distillation using butyric acid. The first distillation eliminates the bulk of the water. The remainder will contain approximately 77% substance. To distill it, 3-6 times the amount is used in the form of an azeotropic mixture.
When opening a container of E236, special care must be taken. When formic acid is stored for an extended period, significant pressure can build up in the container.
Since ancient times, the burning secretions of red ants have been valued by healers for their analgesic, anti-inflammatory and disinfectant properties.
In the enlightened 17th century, the English zoologist John Ray became interested in obtaining a miracle cure and conducted a not entirely humane experiment. The scientist placed several dozen ants in a glass jar. Then he boiled water and passed a stream of steam through the vessel. Subsequent condensation gave a strongly acidic solution. The creator named it formic acid.
Two centuries later, the French chemist Berthelot synthesized the substance from carbon monoxide. The technique was taken as a basis by modern chemists.
The generally accepted designation of the preservative is Formic acid (international synonym is Formic acid). There are also other names:
- Index in the European codification system E 236 (E–236).
- The name according to the systematic nomenclature is methanoic acid.
- In German the following designations are found: Ameisensaure, d-Carbonsaure.
- French synonyms: Acile formique, Acide methanoique.
Type of substance
Food additive E 236 belongs to the group.
In small quantities, the organic substance is synthesized in the human body from methyl alcohol, which penetrates through the respiratory tract and skin.There are several ways to obtain formic acid.
About 35% of the total amount of the substance is produced by the method of alkaline hydrolysis of formamide (mainly for technical purposes).
Additive E 236 for the needs of the food industry is synthesized in two stages. First, carbon monoxide is passed through sodium hydroxide (caustic soda) heated to 1300C. The sodium salt of formic acid (sodium formate) formed as a result of a chemical reaction is decomposed with sulfuric acid and distilled in a vacuum unit. This is the main industrial method for obtaining the substance.
Formic acid is the strongest saturated monocarboxylic acid. In high concentrations, it is capable of dissolving nylon, nylon and other polymers.
Properties

Technical methane acid is used as an anti-icing reagent, mixed into a concrete solution as an anti-frost additive, cleans paint equipment in auto repair shops, and removes oxide formations from copper alloys.
In the European Union, preservative E236 is not approved for use in food products, but is allowed in cosmetics (no more than 5% of the total amount).Approved in Russia, Belarus, EAEU countries.
In the USA it can be used in synthetic food flavorings.
Benefits and harms
The extent of the harmful effects of formic acid on human health depends on its concentration. An aqueous 10% solution belongs to class 3 (moderately hazardous substance).
The permissible daily intake in food products is 3 mg per 1 kg of human weight. The food additive E 236 is completely absorbed by the body, some of it is excreted naturally.
The substance is biodegradable without harming the environment.
Pure formic acid is considered one of the most dangerous fatty acids.
When it comes into contact with the skin, it easily burns through the top layer, causing a chemical burn that does not heal for a long time.The affected area is washed with a solution of ammonia or soda (not water!).
Main manufacturers
The main supplies of the food additive E 236 are carried out by the chemical concern BASF (Germany), which has production sites in 80 countries. The company's motto is “We create chemistry for a sustainable future.” 
A good quality product is produced by the Chinese company GinzhouLvzhiyuanFertilizerFactory, which owns its own laboratory and factory with five production lines.
The domestic market is represented by the Moscow company Kompanent-Reaktiv (awarded with the international Golden Arch award of Europe for high quality products).
The Khimreaktiv enterprise (Nizhny Novgorod) is the largest supplier of technical formic acid.
The benefits of formic acid significantly outweigh the possible harmful effects on the human body. If precautions and recommended doses are observed, the food additive E 236 will not only be a good medicine, but will also ensure the cleanliness of the premises and extend the shelf life of products.

1. As a by-product in the production of liquid-phase oxidation.
This is the main industrial method, which is carried out in two stages: in the first stage, carbon monoxide under a pressure of 0.6-0.8 MPa is passed through sodium hydroxide heated to 120-130°C; at the second stage, sodium formate is processed and the product is vacuum distilled.
Safety
Formic acid is the most dangerous of fatty acids! Unlike inorganic acids like sulfuric acid, it easily penetrates the fatty layer of the skin; washing the affected area with a soda solution must be done immediately!
Formic acid, when even a small amount comes into contact with the skin, causes very severe pain; the affected area first turns white, as if covered with frost, then becomes like wax, and a red border appears around it. After some time, the pain subsides. The affected tissue turns into a crust up to several millimeters thick, healing occurs only after a few weeks.
Vapors from even a few spilled drops of formic acid can cause severe irritation to the eyes and respiratory system.
Chemical properties
