When it is used in the leather industry, the so-called "carbon" leather is obtained, which is not inferior in quality to leather goods or footwear. It is used for bleaching fabrics. In the chemical industry, sulfur dioxide (SO2) is widely used, which is formed during the oxidation of hydrogen sulfide on catalysts or during the combustion of sulfur. Pure S02 is used instead of lime to reduce the acidity of wastewater in many chemical plants.
Concentrated hydrochloric acid
If we consider a solution, then it contains water and, depending on its content (ratio), the proportional component of the product changes. Thus, some product is obtained more pure, and some with a lower concentration. One of the distinguishing factors is high corrosiveness. And when small mechanical particles get into it, it causes a violent corrosion process. It is widely used in industry.
Hydrochloric acid reagent grade (chemically pure)
Characteristics of similar raw materials:
As a rule, the reagent is ready for use. Expiration date 12 months. Raw materials manufactured in accordance with GOST 3118-77 are supplied. Also, the brands GOST 857-96 or GOST 857-95 can be brought.
A solution of chemically pure with a mass fraction of 10% has a shelf life of 5. Supplied in a nominal volume: 500 ml. - 1000ml.
Inhibited hydrochloric acid
Obtained from concentrated aluminum salts (AlCl3, Al (OH) 3, AlCl2) in water. Formed HCl + H2O + 2AlCl3. In the case of an excess of chlorides or at elevated temperatures, a mixture of HCl and hydrazine hydrochloric acid is formed. Hydrazine hydrochloric acid has a characteristic chlorine odor. HCl, H2O and AlCl3 form a mixture.
As a result, it is possible to obtain alkyldithiocarbamates, which, depending on the production method, can be represented by the formula [R4SCH2CH2C (O) C (O)] 3 or [R1SCH2CH (C2H5) C (O)] 3.
In the presence of hydrogen peroxide and hydrogen peroxide, it oxidizes the aldehydes contained in both the solid and liquid phases to the corresponding carboxylic acids, and then these carboxylic acids and their salts are removed from the solution by extraction with an organic solvent, usually water. In addition, another combination of oxidizing agents can be used to remove residual aldehydes, for example, a mixture of hypobromine (hypobromite) and perfluoroethanesulfonic or perfluorotrichloromethanesulfonic.

Hydrochloric acid precursor
(CH3COO) 2Cl - colorless transparent liquid of sour taste; dissolves many substances well. It gradually evaporates in the air. Colorless liquid with the smell of hydrochloric or copper chloride, well soluble in water, poorly - in organic solvents. By chem. S.'s properties to. is close to HCL.
It can also be in the form of a white powder, used as a solution for external use and preparation of dosage forms of drugs in industries.
Hydrochloric acid production
Produced by Russian factories. And by firms licensed by companies such as Krauss-Maffei (Germans) and licensed by the British firm Vickers (England); - production of nitrobenzene, nitrotoluene, acetone, aniline hydrochloride and trinitrobenzene under the licenses of A. Ro "(USA); - sulfuric acid production under license from Otis (USA) and K. Schuzen "(Germany).
Chemicals that are used for industrial purposes in the production of saltwort and hydrofluoric (hydrofluoric) acid must meet the requirements of the Technical Conditions "General Specifications". The suitability of the chemicals used must be confirmed by a sanitary and hygienic certificate.
Storage of hydrochloric acid
Produced in containers for petroleum products. For this purpose, it is necessary to use containers that exclude the ingress of oil products on it. Tanks for hydrochloric acid solutions should be located in hangars, specialized and with ventilation with a mechanism for air inlet and outlet. If there are materials in the solution, the raw material is chemical. In this case, it is necessary to take measures that exclude the fact that paints and varnishes get into the solution.
In case of overflow of raw materials from the barrel machine into cubes. At the work site, containers should be provided for: - collecting spilled salt or sulfuric acid; - neutralization of to-you formed after its use; - disposal of used materials (solid or liquid).
Neutralization of hydrochloric acid, increase in pH. To protect steel against corrosion, inhibitors of the Enolite type are used.
Neutralization with alkali occurs when the concentration of the HCl substance is less than the concentration of the NaOH base. For the neutralization reaction, an HCl concentration of 0.005 mol / l is sufficient, and for the formation of alkali - 0.001 mol / l. However, this reaction only occurs when there is an excess of sodium hydroxide. Therefore, it requires twice the amount of hydroxide to carry out. Thus, in the course of the reaction, the alkali is neutralized not with water, but with sulfuric acids.

hcl is a kind of raw material. It happens:
- hcl hydrochloric acid (gallic acid),
- ph4 hydroxide - a type of product,
- pb hydroxide or chloric.
hcl and hcla are hydrochloric acid. Colorless hygroscopic crystals. can be obtained by the interaction of sulfuric or nitric acid oxides. For industrial production of hcl in laboratory conditions, it is obtained by mixing strong hydrochloric and strong sulfuric acid oxides while heating. hcl is very easily oxidized to almost any substance with which it reacts, therefore, when working with it, it should not be allowed.
Hydrochloric acid high purity
Purified and can be tested for sodium and potassium ions. To do this, it is diluted about 5 times, and then water is evaporated from the resulting solution until a clear solution is formed. If the solution contains Na + and K +, then when potassium permanganate is added, a pink solution is formed, which becomes discolored when barium chloride is added, if sodium ions are contained, then the solution becomes discolored, if potassium ions, then the color does not change.

Disposal of hydrochloric acid
Recycling generated during the operation of chemical shops and warehouses is the most difficult stage in the technology of production.
During neutralization, for example, after draining concentrated, sulfuric and phosphoric acid from the tank, the residues are diluted with water in the tank, filled in the tank and sent for neutral processing. When neutralizing hydrochloric, sulfuric, as well as phosphoric, nitric bulk acids, different disposal methods can be used: neutralization with alkali or water, neutralization with gaseous calcium oxide or carbon dioxide, and flaring.

Abgas hydrochloric acid
The off-gas products obtained during the processing of brines (brine-concentrates) are characterized by a higher degree of purity in comparison with conventional solutions: they have higher concentrations of the main components, as well as a higher content of dissolved gas. The off-gas can be processed into a salt brine (sodium chloride in the form of a solution diluted in water) and into hydrogen chloride.
It is used in the chemical industry for the production of organofluorine compounds, synthetic rubber, and for the production of acetylene. It is used to remove hydrogen sulfide from gas mixtures, at various oil industry enterprises, in boiler plants of power plants.
Hydrochloric acid of analytical grade or chNDA
This is a solution of hydrogen chloride. The concentration of hydrochloric acid salt is 25-35%. Chemical composition and color meet the requirements of GOST 857-96. ChDA is packaged in dark glass bottles of 250 and 1000 ml. Expiration date - 24 months.
ChNDA, GOST 19522-74 Technical salt is a by-product in the extraction of table salt and can be used as a component and raw material for the production of chemical reagents. In its composition, it differs from natural water only in the percentage of salts.
Hydrochloric acid color
The color is bright yellow, has a chlorine smell. In air, the gas, due to its increased hygroscopicity, as well as its ease in rupture, at normal pressure is absorbed by water by 100%, forming hydrochloric or chloride (hydrochloric) water HClO. At elevated pressure, for example, in a cylinder at a pressure of 5 atm, it decomposes into hydrogen, chlorine, which snap off into two layers in the cylinder.
Hydrochloric acid toxicity
When working, it is necessary to observe safety precautions. Improper handling can cause burns. Chloric, trichloroacetic and acetic salts of acid. to a certain extent toxic, and carbon monoxide is poisonous. The most dangerous concentration of salts and nitric acid in the air is 0.01 and 0.005 mg / l, respectively.
It is not used in its pure form. It should be diluted to the required concentration for ease of use, should not contain any impurities and, in addition, should not contain more than 0.2% hydrochloric or 10% mercury chloride in terms of HgCl2.
The valency of hydrochloric acid is two.
And with sulfuric - three. You can arrange the coefficients using the electronic balance method.
It exhibits oxidizing properties in relation to potassium permanganate. In this case, KMnO 4 acts as an oxidizing agent. During the interaction of HCl and KMnO 4, a complex compound is formed - a red-brown precipitate of red-violet color of manganese (I) sulfate MnO 2 (oxygen is released during its decomposition): HCl + KMnO4 = MnSO 4 + Cl 2 + KMnCl 2.
