Synthetic hydrochloric acid (35-37%)

Technical synthetic hydrochloric acid (hydrochloric acid) (Hydrochloric acid) - solution of chloride hydrogen in water, strong monobasic acid. The colourless, "smoking" on air, strongly caustic liquid (technical hydrochloric acid yellowish because of _{impurity Fe, Cl2}, etc.).
The maximum concentration at 20 °C is equal to 38% on weight, density of such solution of 1,19 ^g/cm3. Salts of hydrochloric acid are called chlorides.

Hydrochloric acid is received dissolution of gaseous chlorohydrogen in water.
In the industry hydrochloric acid is received by the following methods:

• sulphatic - receiving chlorhydrogen action by the concentrated chamois of acid on sodium chloride;
• synthetic - receiving chlorhydrogen combustion of hydrogen in chlorine;
• from abgaz (collateral gases) of a number of actions.

but the first two ways lose the industrial value.

More than 90% of hydrochloric acid in the CIS receive them the abgazny HCI chlorohydrogen which is formed at chlorination and dehydrochlorination of organic compounds, pyrolysis of organochlorine waste, chlorides of metals, receiving the potash not chlorinated fertilizers, etc. now.

Application

• in hydrometallurgy and a galvanoplasty (etching, a dekapirovaniye), for cleaning of a surface of metals during the soldering and a tinning, for receiving chlorides of zinc, manganese, iron, etc. metals;
• in mix about surfactant it is used for cleaning of ceramic and metal products (inhibited acid is necessary here) of pollution and disinfection;
• in the food industry it is registered as the regulator of acidity, a food additive of E507.

Bulk hatches of tanks, the container and traffic jams of barrels have to be pressurized by rubber or polyethylene laying, as when sending to consumers (filled with acid), and at return to the supplier of empties.
Level (degree) of filling of tanks, containers, barrels and large bottles calculate taking into account the maximum use of the loading capacity (capacity) and volume expansion of a product at possible temperature drop along the line.

Technical synthetic hydrochloric acid about compliance with rules of transportation of dangerous freights is transported:

• in bulk in railway tanks;
• packed into containers, barrels and large bottles in boxes - by rail in the covered cars car sendings;
• packed into containers, barrels., large bottles - a motor and water transport.
