In agriculture, as a liquid fertilizer containing ammonium nitrogen 20.5%. From an economic point of view, this type of nitrogen fertilizers are the cheapest. The highest effect of the ammonia water is achieved by making the fall in the soil, because not washed away by precipitation, or preplant during the spring. Aqueous ammonia when applied to the soil can be used for all business culture. Nitrogen ammonia better retained soil than solid ammonium nitrogen fertilizers. Ammonia water - good fertilizer for potatoes, sugar beet, cereals and vegetable crops, perennial grasses. By increasing the yield of ammonia water is not inferior to solid ammonium nitrate fertilizers.

In animal husbandry - for ammoniation of forages.

Wood's alloy is used in precision casting, in the operations of bending thin-walled tubes, as rods melted in the production of hollow bodies way of electroforming to fill metallographic polished sections, in sensors of fire alarm systems, as a low-temperature heating bath in chemical laboratories and others.

Rose’s alloy is used for semiconducting engineering, in cutouts, in radiotechnics as tin-lead alloy with bismuth 50, for soldering details susceptible to overheating, for aluminium soldering, aluminium with copper and its alloys in erection joints, aluminium alloys against each other, for soldering and tinning copper, nickel, brass, bronze, copper and copper-nickel alloys with silvered ceramics, for soldering silvered details, for soldering and tinning jewellery, etc.

It is used as a hardener resins. Thick transparent viscous liquid, soluble in butyl alcohol, nitric acid and insoluble in ethanol, benzene. Hygroscopic.
Used to "hot" curing epoxy resins in various industries. It provides a high strength, thermal shock resistance, chemical resistance of the cured systems. Not toxic

Trietanolamintitanat hardeners in combination with a wide range of applications. It is used in construction, ships, mechanical engineering, aircraft industry. Such compositions are an excellent protection of concrete and metal corrosion, based on them receive various hermetic compositions and paint products. On the demand for resins in various sectors affects their operability. So in the original state they usually represent liquids that can be cured. Thus virtually no shrinkage and release of byproducts.

Vitamin 4 - choline, lecithin is a part - the most common phospholipids. The composition also includes lecithins linoleic, palmitic and oleic acids. Sensitive to lack of choline poultry and pigs.

Choline chloride - used in the composition of compound feed for livestock and poultry as a source of choline. Choline (vitamin B4) does in the body's vital functions, it is a substance of which the body is formed acetylcholine - one of the major mediators of nervous excitement. The lack of choline in the body of animals leads to the development of fatty infiltration and hemorrhagic degeneration of the liver and kidneys, thymus involution.

Choline is part of the phospholipid lecithin which is an important part of the body's cells. It plays an important role in the metabolism of phospholipids; involved in the synthesis of phospholipids in the liver. Choline is one of the main representatives of the so-called lipotropic substances that prevent or reduce fatty liver. It serves as an important source of methyl groups necessary for the body occurring biochemical processes.

The mechanism of action of choline is two things: first, it helps brain cells to grow better in the second part of choline is converted into a substance acetyl choline, a signal substance of the nervous system, which helps in learning and intellectual processes.

In practice, the need for increased choline at a high content of fat in the diet (which is particularly important for ensuring high hatchability), with the additional administration of vitamin B5 in the diet (choline antagonist) and providing minimum rate methionine diet.

Symptoms of deficiency of choline in the body: a sharp decline in productivity in chickens inflammation and an increase in the curvature of the joints (perozis), fatty liver and its subsequent degeneration, enlarged kidneys.
