Ammonium sulfate is an inorganic sulfate salt obtained by reaction of sulfuric acid with two equivalents of ammonia.A high-melting (decomposes above 280℃) white solid which is very soluble in water (70.6 g/100 g water at 0℃; 103.8 g/100 g water at 100℃), it is widely used as a fertilizer for alkaline soils. It has a role as a fertilizer.

Ammonium Sulphate – A By-product of Coal Coking Process. Ammonium sulphate is produced as a by-product during removal of ammonia (NH3) from the raw coke oven gas generated during the coking of the metallurgical coal in by-product coke ovens. Its industrial production began over a century ago, as by-product in gas cleaning in coke and coal gasification plants. Ammonium sulphate is produced ...

Ammonium sulfate (sometimes abbreviated as AS or AMS) has been produced for more than 150 years. 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

Ammonium sulfate decomposes upon heating above 250 °C, first forming ammonium bisulfate. Heating at higher temperatures results in decomposition into ammonia, nitrogen, sulfur dioxide, and water. As a salt of a strong acid (H 2 SO 4) and weak base (NH 3 ), its solution is acidic; pH of 0.1 M solution is 5.5.
