Aluminum chloride

Aluminum chloride, also called aluminum chloride, is a salt of two compounds - hydrochloric acid, as well as aluminum itself. Aluminum chloride has the chemical formula AlCl3. Distillation of the connection occurs at a temperature of 183 ° C - this is the case if the pressure is normal. When the pressure rises, the substance begins to melt already at a temperature of 192.6 ° C.

As a rule, aluminum chloride is readily soluble in aqueous solutions, a total dissolution of 44.38 grams of material occurs in a one-hundred-gram volume of water at a temperature of 25 ° C. During hydrolysis, the substance is smoked in moist air with the evolution of HCl. In the anhydrous state, aluminum chloride appears to be colorless single crystals, which at temperatures up to 440 ° C acquire the properties of a dimer - they turn into liquid or vapor. When the temperature is raised to 800-1000 ° C, the substance is a stable monomer.

The most important way of obtaining the compound is the action of Cl2 and CO on anhydrous bauxites and kaolins. Such reaction is carried out in industrial production in special furnaces of mine type. There are other methods of obtaining, for example, the interaction of boron trichloride with aluminum phosphide during the reaction conducted at 900 ° C leads to the formation of aluminum chloride. All reactions associated with the preparation of the compound are carried out with the participation of a reducing agent, which carbon acts.

Anhydrous aluminum chloride interacts with many organic and inorganic substances. With inorganic forms, it forms addition products, such as NH3. With organic aluminum chloride forms acid chlorides, as well as a variety of ethers.

Crystallization from aqueous solutions leads to the formation of a yellowish white substance that becomes fluid in the open air, it is aluminum chloride hexahydrate.

Aluminum chloride is an indispensable catalyst in the implementation of organic synthesis, an example of this is its use in conducting Friedel-Crafts operations. It acts as an intermediate in hydrolysis production for the isolation of A1 from alloys and the production of A1 of super-pure quality. The use of hexahydrate, as well as its solutions, is common in wood processing, water treatment technologies.

Since aluminum chloride is widely used in the industrial segment of the economy, its annual production in the world is constantly growing and at the moment is estimated at about 200 thousand tons.

At present, aluminum chloride is the most in demand in such areas as pharmaceuticals and perfumes. This substance is widely used in the manufacture of drugs that counteract hyperhidrosis - increased sweating of the body. Its derivative, aluminum chloride, Etiaxil hexahydrate, is used as an essential basis for the production of deodorants and antiperspirants. In pure form, this substance is colorless crystals, and its chemical formula is written as H12AlCl3O6. The use in this capacity should be accompanied with extreme caution, since the cause of hyperhidrosis can be a variety of factors: nervous and ectodic disorders, kidney disease and others. In this case, do not mindlessly acquire and use everything that contains Etiaxil hexahydrate, although what in one case did not help, in another case will help. The fact is that in all these agents, a wide variety of combinations of hexahydrate and other components can be used.

To obtain the expected effect of the use of preparations and products with Etiaxil content, it is necessary to select them precisely, taking into account the features of each type of skin and the degree of manifestation of the sweat.
