Hydrochloric acid Technical (not less than 31.5%)

Hydrochloric acid is widely used in various sectors of the national economy:

In the chemical industry :

ü for obtaining chlorides of Mn, Fe, Zn, etc., for etching metals, cleaning the surfaces of vessels and wells from carbonates, processing ores, in the production of rubber, sodium glutamate, soda, etc.

ü HCl is used for the regeneration (reduction) of Cl2, in organic synthesis (production of vinyl chloride, alkyl chlorides, etc.), as a catalyst (e.g., in the production of diphenylolpropane, alkylation of benzene).

ü in the production of organic dyes, various chloride salts, activated carbon, precipitate, synthetic rubber, etc.

In hydrometallurgy and electroplating (etching, pickling):

ü for cleaning the surface of metals during soldering and tinning, for obtaining chlorides of zinc, manganese, iron and other metals.

ü When mixed with surfactants, it is used to clean ceramic and metal products (an inhibited acid is required here) from contamination and disinfection

In the food industry :

ü as an acidity regulator, food additive E507. Used in the production of seltzer (soda) water.

ü in the production of sugar, glucose, and in the saponification of fats and oils

In medicine , as a component of gastric juice for diseases associated with insufficient acidity of gastric juice.

In the light and textile industries for textile finishing, leather tanning, wool processing, and wood hydrolysis

In agriculture for the preservation of feed

Packaging and storage

Technical synthetic hydrochloric acid is poured into special rubberized tanks of the sender or recipient, rubberized containers, polyethylene barrels with a capacity of 50 dm3 and glass bottles with a capacity of 20 dm3 in accordance with current regulatory documentation.

Filling hatches of tanks, containers and barrel plugs must be sealed with rubber or polyethylene gaskets, both when shipped to consumers (filled with acid) and when empty containers are returned to the supplier.

Technical synthetic hydrochloric acid is stored in sealed containers of the manufacturer and the consumer, made of materials resistant to hydrochloric acid.

Transportation

Technical synthetic hydrochloric acid is transported in accordance with the regulations for the transportation of dangerous goods:

- in bulk in railway tanks ("Rules for the Transportation of Dangerous Goods No. 340", Part 2, Section 41);

- packed in barrels and bottles in boxes - by rail in covered wagons in wagon-size shipments ("Rules for the Transportation of Dangerous Goods No. 340", Part 2, Section 42);

- packed in containers, barrels, bottles - by road and water transport

Product Safety Information

Technical synthetic hydrochloric acid is a caustic liquid that is chemically stable. It "fumes" in air due to the release of hydrogen chloride and its attraction to atmospheric moisture, forming an acidic mist.

Metals located in the voltage series to the left of hydrogen (Al, Zn, Fe, Co, Ni, Pb, etc.) displace it from hydrochloric acid, which can lead to the formation of explosive hydrogen-air mixtures.

Safety measures - avoiding contact of hydrochloric acid with the above metals by using anti-corrosion coatings, purging with nitrogen and testing the gas phase from equipment and pipelines for explosiveness before carrying out fire work
