    • White crystalline powder

  • General Description
    • White odorless solid. Sinks and dissolves in water.

  • Air & Water Reactions
    • Dissolves in water with evolution of some heat.

  • Reactivity Profile

    Ammonium sulfate is acidic in aqueous solution. When a little Ammonium sulfate is added to fused potassium nitrite, a vigorous reaction occurs attended by flame [Mellor 2:702 1946-47].

  • Synthesis
    • After ammonium hydroxide neutralized with sulfuric acid, crystallization, centrifugal separation and dry to get. Neutralizational process, neutralization reaction of ammonia and sulfuric acid is performed at about 100 ℃, the generated ammonium sulfate crystals slurry separated by centrifugal separation and dried to obtain ammonium sulfate product. its 2NH3+H2SO4→(NH4)2SO4 Recovery method is to recycle ammonia from the coke oven gas, and then performed neutralization reaction with sulfuric acid to obtain.

  • Usage
    • 1. Mainly used as fertilizer, for various soil and crop. 2. For the analysis reagents, also for protein precipitation. 3. Used as a flux, fabric fire agent, etc. 4. Used as a fertilizer, also can be used as flux, fire retardant fabric, as the salting-out agent, osmotic pressure regulating agents in medicine. 5. Used as raw materials of hydrogen peroxide , ammonium chloride, ammonium alum and production in chemical industry, as a flux in the welding industry. As a fire retardant in textile fabric industry. As a plating bath additives in electroplating industry. As a nitrogen fertilizer in agriculture, for general soil and crops. As a dough modifier, yeast nutrients in food grade product. 6. Dough modifier; yeast nutrients. Used as nitrogen source of yeast culture in fresh yeast used production, the dosage is not specified. As yeast nutrients in bread, the amount is about 10% (approximately 0.25% of the amount of wheat flour). As a processing aid listed in GB 2760-90.
