Iron chloride 6-water

 

Synonyms: Iron treharne, iron chloride, iron chloride, iron III chloride hexahydrate, iron chloride hexahydrate,

Iron III chloride 6-water (Iron chloride, iron treharne) FeCl3 · 6H20 - soft crystal weight or pieces of yellow-brown color.

 

Ferric chloride - the average salt of trivalent iron and hydrochloric acid. In view of this chemical raw is a soft crystalline mass of rusty-brown-black color. Boiling temperature is 319 ° C melting point - 309 ° C. ferric Chloride is formed by heating iron with chlorine. It can also be obtained as a byproduct in the production of titanium chloride TiCl4 and aluminum chloride AlCl3. Another method of obtaining ferric chloride - hot chlorination or oxidation of FeCl2 solution with subsequent evaporation of the solution FeCl3.

 

Sphere application ferric chloride is quite wide. It is used as a coagulant for water purification, as catalyst in organic synthesis, to stain in the process of dyeing fabrics, and also for preparation of iron pigments and other salts of iron. Another solution of ferric chloride used for etching printed boards.

 

Wide enough distribution of ferric chloride was obtained as a coagulant in the purification process industrial and municipal wastewater. In comparison with other coagulants such with aluminum sulfate, this chemical the product has an important advantage - chloride iron is endowed with a high speed deposition of various impurities. In the result of the hydrolysis of ferric chloride forms a slightly soluble hydroxide of iron. In the process of education admire various organic and inorganic impurities, forming a loose flakes, which can be easily removed from acidalia drains. Water purification ferric chloride reduces the content of soluble impurities up to 25 percent, and insoluble to 95 percent. In the process of the purification of waste industrial and urban waters toxic compounds and microorganisms get destroyed with sodium hypochlorite.

 

Due to its pronounced acid properties, ferric chloride is used as the catalyst in processes of organic synthesis, when obtaining heat-resistant resins and oxidation of bitumen. Iron chloride is a vigorous chlorinating agent, because it is used for selective extraction of some components of ores. In particular, this chemical raw materials needed in aromatic hydrocarbons to electrophilic substitution. It is also well known the use of aqueous solutions of ferric chloride. Having a relatively soft traveline properties, they are used in electronic industry and instrument industry for the etching of printed circuit boards, metal parts and copper foil. Used ferric chloride and construction. It is used as an additive to Portland cement to accelerate the process of setting. Additive ferric chloride greatly increases the strength of concrete.

 

 

Iron III chloride the hexahydrate is used:

 

• with its use highlights the natural water in water treatment systems;

• removed oil from drains fat and oil plants;

• he used in wastewater treatment of leather and fur enterprises from the chromium compounds;

• to mitigate drinking water;

• and in organochlorine synthesis

• for digestion printed circuit boards in the electronic industry

• instrumentation,

• as the original substance to obtain the other compounds of Fe,

• as a component toning solutions photos

• as a mordant in the dyeing,

• industrial water treatment,
