Ferric chloride - average ferric salt and hydrochloric acid. In this kind of chemical raw materials is a soft crystalline mass rusty-brownish-black color. Its boiling point is 319 ° C, the melting point of - 309 ° C. Ferric chloride produced by heating iron with chlorine. It can be obtained as a byproduct in the production of titanium chloride TiCl4 and aluminum chloride AlCl3. Another method for preparing ferric - hot chlorination or oxidation of FeCl2 solution, followed by evaporation of FeCl3 solution.
Scope of ferric chloride is wide enough. It is used as a coagulant for water purification, as a catalyst in organic synthesis as a mordant in dyeing process, as well as pigments for the preparation of iron and other iron salts. Another ferric chloride solution is used for etching printed circuit boards.
Suffice widespread ferric chloride obtained as a coagulant in the treatment of industrial and municipal wastewater. Compared with other coagulants, in particular with aluminum sulfate, a chemical product that has an important advantage - iron chloride is endowed with a high deposition rate of various impurities. Hydrolysis of the ferric chloride forms a sparingly soluble iron hydroxide. The process of formation of trapped various organic and inorganic impurities, forming a friable flakes that can be easily removed from the cleaned waste water. Such flakes, density of 1001-1100 g / l and 0.5-3.0 mm in size, have a rather large surface with excellent sorption activity. In the process of their formation are included in the structure of suspended solids (large microorganisms planktonic cells yl, plant residues), colloidal particles, and part of the ion contaminants associated data on the particle surface. With this product, the slurry deposition process is much faster and deeper. Another advantage of ferric chloride - its beneficial effect on the biodegradation of the sludge. For quality wastewater per cubic meter require 30 g of ferric chloride. Clean water reduces the ferric chloride content of soluble impurities up to 25 percent, and insoluble to 95 percent. In the process of industrial wastewater and municipal water toxic compounds and microorganisms are destroyed with sodium hypochlorite.
Due to their pronounced properties acidic ferric chloride is used as a catalyst in organic synthesis processes, when receiving heat resistant resin and the oxidation of petroleum bitumen. Iron chlorine - energetic chlorinating agent, so it is used for the selective extraction of certain ores components. In particular, a chemical raw material required for the reaction of aromatic hydrocarbons, electrophilic substitution. It is also well known to use aqueous solutions of ferric chloride. Having sufficiently soft etching properties, they are used in electronics and instrumentation for etching printed circuit boards, the metal parts and the copper foil. It used ferric chloride and construction. It is used as an additive for Portland cement to accelerate the setting process. The addition of ferric chloride significantly increases the strength of concrete. Use this product in other spheres of human activity, in particular:
• use it to lighten the natural water in water treatment systems;
• remove the oil from the waste oil and fat plants;
• it is used in waste water treatment and leather fur enterprises of chromium compounds;
• to mitigate the domestic hot water;
• as well as organochlorine sintezekg
