Ammonium Sulphate

Ammonium Sulphate

CAS No.:7783-20-2

Molecular Formula: (NH4)2SO4        Molecular Weight:132.14

Structural Formula:

Properties:

Ammonium Sulphate has PH value is 5.5 in 0.1M solution. Density 1.769 g/cm3 (20°C). Ammonium Sulphate is hygroscopic; soluble in water; insoluble in acetone, alcohol and ether. Main active ingredients are 21% nitrogen and 24% sulfur, so it can be described as NPK 21-0-0 24S. Generally, it is a by-product from chemical (cyanuric acid, capro, acrylonitrile, sodium cyanide, monosodium glutamate-MSG, methyl methacrylate-MMA, etc.) or steel plant. Steel Grade (also call Coke-ovens Grade) is fine white powder. After processing it can be white granular or flake. Caprolactam Grade is colorless (achromatic) crystalline or yellowish crystals.

Usage:

Agricultural

Ammonium Sulphate is one of the most common use and most typical inorganic nitrogen fertilizer. Ammonium Sulphate is the best fast release, quick acting fertilizer, which can be directly used for a variety of soil and crops. It can also be used as kinds of seed fertilizers, base fertilizer and additional fertilizer. It is particularly suitable for the soil which lack of sulfur, low chlorine tolerance crops, sulfur-philic crops.

Ammonium Sulphate is very popular in Japan, Southeast Asia, as well as northeast China where plant premium rice. It is suitable for the rice seedling, the growth of tea, grass, vegetables, and fruit trees, effectually rapid promoting the growth of grain, vegetables, fruits, grass and other plants. It has more efficiency than urea, ammonium bicarbonate, ammonium chloride, ammonium nitrate etc. Large granular Ammonium Sulphate can also serve as raw material for compound fertilizer. As feed additives, it provides the nutrients of non-protein nitrogen to ruminants. Ammonium Sulphate also used for fish culture in some areas.

Attention:

1 Try not to use Ammonium Sulphate in paddy fields.

2 Ammonium sulphate are acidic fertilizers. It can increase the acidity of the soil, Therefore should pay attention to use in acidic soils with alkaline fertilizer, such as plant ash, phosphate rock powder or calcium magnesium phosphate and so on. Use in neutral and alkaline soil in order to prevent calcium ion combined with sulfate ion to insoluble calcium sulfate (gypsum), caused by soil hardened, and should apply with organic fertilizer.

Industrial

In chemical industry, Ammonium Sulphate as the raw materials of hydrogen peroxide, ammonium alum and ammonium chloride; and the minor ingredient of ammonium persulfate, lysine.

In welding industry, Ammonium Sulphate as a welding agent.

In textile industry, Ammonium Sulphate as a flame retardant.

In electroplating industry, Ammonium Sulphate as a plating bath additive.

In dyeing industry, Ammonium Sulphate as a dyeing auxiliaries of acid dyes.

In leather industry, Ammonium Sulphate as a deliming agent.

In food industry, Ammonium Sulphate as a dough conditioning agent (fermentation medium), and a catalyst of sauce food.

In pharmaceutical industry, Ammonium Sulphate as a salting-out agent can purifying proteins by precipitation

In pesticide industry, Ammonium Sulphate as an adjuvant agent. Add in water soluble insecticides, herbicides, and fungicides, such as 2,4-D Amine Salt, glyphosate, and glufosinate herbicides.

Packing:

20kg, 25kg, 50Kg PP woven bag with PE inner bag or composite plastic woven bag.1MT (1000kg) or 1.1MT (1100kg) jumbo bag. Shrink-wrapped with pallet is available.

Kept in dry and place, avoid moisture, water, rain and fire, normal transportation.

In the transportation and outdoor storage, Ammonium Sulphate should be kept away from moisture, insolation, rain & high temperature. Should storage in flatness ground within a ventilating low-temperature dry warehouse. In order to prevent deterioration, strictly prohibit store nearby alkaline substances, such as lime, cement and plant ash. The stacking height should be less than 7 meters.

Storage

Store inside, away from rain and heat. The hygroscopic nature of most water soluble fertilizers require that extreme care should be taken to limit product exposure to moist and/or humid conditions. Pressure setting can also occur when these products are stored / stacked in multiple layers. Pressure setting and/or caking only influences the free flowing nature of the product, but does not bear any negative impact on the product’s specifications or performance.

21N + 24S ( 60 SO3)

AS-StandardAmmonium sulphate produced by OCIAgro contains ammonia nitrogen and soluble sulphur. Nitrogen is presented entirely as ammonia, thus reducing leaching during wet periods. It is a commonly used fertilizer in agriculture for soils with sulphur demand, for example in crops of forage plants or potatoes. Both in Southern Europe and in other countries, ammonium sulphate is often used in citrus crops, coffee, rice, tea, bananas, pineapple, sugar beets or soybeans. It is a fertilizer that can be used as main component in the process of fertilizing and / or blending. NICagro provides two ranges of products whose main difference is the grain size, having granular crystalline ammonium sulphate and ammonium sulphate. The crystalline variety is formed by the SA Crystalline and SA standard; while the range of the granular product is formed by SA-granular (3), SA-granular (2) and SA-granular (2S). For further details, please refer to product specification sheets on our website. The granule size determines the specific characteristics of spreading as well as the applications possibilities. It is important to adjust the spreader for the correct settings.

Ammonium Sulphate fertilizer is characterized by its fast acting “application-results”. Although crops can absorb ammonia nitrogen directly, the highest part of absorption will occur at the time ammonia is converted into nitric nitrogen because of the reactions with the soil; being both soil temperature and humidity, factors that set the pace and speed of the conversion. It is important to note that ammonia nitrogen gets its process of leaching-volatilization slowed when combined with other soil particles such as clay minerals and organic matter.
