Name: ammonium sulfate

Other names: ammonium salt of sulphuric acid, ammonium sulfate Formula: (NH4)2SO4 Group: industrial chemistry Look: salt, white or transparent crystals Supplier: LLC Company Plazma ® Packaging: bags of 25-50 kg. Producer: Russia Ammonium sulfate represents salt, white or transparent crystals well soluble in water, insoluble in acetone, ethanol and ether.

Density is 1,769 g/cm ³. Melting temperature - 235-280 °C, decomposition temperature - 218 °C.

The industry receives ammonium sulfate in the form of crystals at interaction of ammonia and sulphuric acid, both direct way, and way of oksimirovaniye of cyclohexanone and neutralization of sulfate ether and free sulphuric acid ammonia, as a result of Beckman's regrouping by production of caprolactam.
Also ammonium sulfate is ammonia catching product sulphuric acid when coking coal, in metallurgical industry, by production of caprolactam. According to production coke-chemical sulfate and metallurgical ammonium sulfate have essential impurity of connections, even heavy metals.

Use of ammonium sulfate.

Agriculture.
Ammonium sulfate - one of the nitrogen-sulfur fertilizers which are widely applied in agriculture, contains 21% of nitrogen in ammonium form and 24% of sulfur. Hygroscopicity its weak therefore at prolonged storage it does not slezhivatsya and keeps flowability. Provides considerable gain of harvest of tea, rye, potatoes, cotton, rice, oats, sugar beet. With success competes with the best nitrogen fertilizers. Ammonium sulfate, thanks to the ammonium form of nitrogen compatible to sulfur, prevents accumulation of nitrates by 3 times, reduces the content of radionuclides in plants twice. It can be applied in the contaminated territories.

It is used under everything crops (from potatoes to citrus) on chernozems and gray soils. Fertilizer possesses valuable quality - low migratory ability as the cation of ammonium is actively absorbed by the soil and it protects it from washing away. Therefore ammonium sulfate is recommended to bring on light-textured soils, at irrigation i.e. where there is potential danger of loss of nitrogen of fertilizer at the expense of the migratory phenomena. Ammonium nitrogen of ammonium sulfate is acquired by plants. Sulfur is necessary for food of all cultures as it is part of some essential amino acids synthesized by plants.

In biochemistry reprecipitation by ammonium sulfate is the general method of purification of proteins.
In the food industry it is registered as food additive of E517 emulsifier.
In means of suppression of the fires ammonium sulfate is applied as fire-retarding agent.
It is used in technology of chlorination of water with ammoniation, entered into the conditioned water several seconds prior to chlorine, with chlorine forms chlorammines - connecting free chlorine thanks to what formation of chlororganic chemistry harmful to human body is considerably reduced, the chlorine consumption is reduced, corrosion of pipes conduit decreases.
In mining industry - as gel-forming component at preventive processing of the developed space, ammonium sulfate is entered into composition of explosive for decrease in combustibility and elimination of danger of spontaneous ignition.

Also ammonium sulfate is applied to production:
- herbicides;
- forages for animals;
- dressing;
- construction isolation.

Ammonium sulfate safety requirements (ammonium sulfate) of GOST 9097-82.
Ammonium sulfate - nonflammable substance. When heating to 235 °C it is capable to decay with release of ammonia and trioxide of sulfur. Apply antidust respirator and tarpaulin mittens to protection against dust.

Packaging, transportation and storage.
Ammonium sulfate is packed into four - six-layer paper bags, and also into open plastic bags weighing 40-50 kg and unpacked (in bulk).
It is transported by all means of transport except for aircraft, in the covered vehicles according to the rules of transportation of load existing on transport of this look. Ammonium sulfate is transported in bulk in specialized hopper-cars, and also in the covered cars or cars covered by bed curtains.
Ammonium sulfate is stored in the closed warehouse excluding hits of rainfall.
Warranty period of storage - 6 months from the date of production.

LLC Company Plazma ® carries out supply of fertilizers from warehouse in Kharkiv in terms and for reasonable prices, on conditions, favorable to you.
