Ammonium Sulfate
Ammonium sulfate, also called diammonium sulfate or sulfuric acid diammonium salt, is a white crystalline solid with no smell. It tastes salty. The compound dissolves easily in water but will not dissolve in alcohol or acetone. It readily absorbs water, so if it’s exposed to moist air, it will “scab” on the damp surfaces. When ammonium sulfate reacts with alkaline substances, it gives off ammonia gas. Finally, ammonium sulfate is a fertilizer that’s sometimes used in making homemade explosives.
Product: Ammonium Sulfate (caprolactam grade)
Nitrogen：21%min
Sulphur：24% min
Free fatty Acid: 0.03% max
Moisture：1.0% max
Appearance：white crystal
The chemical compound ammonium sulfate is primarily used in fertilizers but is important in other industries as well. While it isn’t considered highly hazardous to humans, there are some important precautions to take if you’re using it.
