Its high solubility provides versatility for a number of agricultural applications. Initially, it was made from ammonia released during manufacturing coal gas used to illuminate cities or from coal coke used to produce steel. Today, manufacturers make it by reacting sulfuric acid with heated ammonia. To get the crystal size best suited for the application, they control the reaction conditions by screening and drying the particles until achieving the desired size.
Some materials are coated with a conditioner to reduce dust and caking. Byproducts from various industries meet most of the current demand for ammonium sulfate. For example, the nylon manufacturing process produces ammonium sulfate as a co-product. In another, certain byproducts that contain ammonia or spent sulfuric acid are commonly converted to ammonium sulfate for use in agriculture. Although the color can range from white to beige, ammonium sulfate is consistently sold as a highly soluble crystal with excellent storage properties.
As described earlier, particle size can also vary depending on the intended purpose. Agricultural use. Due to unavoidable dissipative processes during the fast reaction, the product from reaction crystallizers is significantly finer and therefore cheaper than the higher quality product from DTB crystallizers.
A comparable process for avoiding sulfur waste is also used in the purification of coke oven gas. Flue gas desulfurization produces ammonium sulfate as a byproduct.

The basics of Ammonium Sulfate Ammonium sulfate NH4 2SO4 is a product manufactured on a large scale and used mainly as a nitrogen fertilizer in agriculture. Downloads Application Report - Ammonium sulfate Centrifuges.
North America. The DTap vaccine, which protects children from diphtheria, tetanus, and whooping cough, uses ammonium sulfate for this purpose. Hazards of Use. Ammonium sulfate is potentially dangerous to both people and the environment, so it requires care in its use. It can cause severe irritation and inflammation of the respiratory tract if inhaled. Contact with the skin or eyes will cause irritation, redness, itching, and pain. It may also be a neurotoxin, meaning it can cause confusion and behavioral changes.
Use ammonium sulfate only in a well-ventilated area or with a personal respirator. Also, wearing boots, gloves, and an apron or coveralls made of an impervious material like PVC will prevent skin contact. Any work area should be outfitted with an eyewash station and emergency shower in case of accidental exposure. While ammonium sulfate is used as a fertilizer and therefore is readily available, it should not be used lightly.
