Features
Industrial ammonium sulphate is white or light grey crystal. It is hydroscopic,and apt to dissolve in  ater(not in alcohol or acetone),and it will become solid blocks when absorbing moisture. The aqueous  olution is alkalinous. It reacts with alkali to release ammonia gas.
Storage and transportation
Stored in cool,dry and ventilated warehouse. It must not be put together with Alkali stuffs,such as lime,cement,etc.Do not expose it to sunlight and rain during transportation .Do not damage the packing   bags.
Uses
(1)Ammonium sulfate is mainly used as fertilizer for a variety of soil and crops.
(2 )can also be used in textile, leather, medicine and so on.
(3 )consumption from the industrial ammonium sulfate ammonium sulfate dissolved in distilled water,

except the addition of arsenic and heavy metals in solution purification agents, filtration, evaporation, cooling crystallization, centrifugal separation, drying. Used as food additives, as dough conditioner, yeast nutrients.
(4 )used in biochemistry, common salt, salting, salting initially be upstream from the fermentation products of purified proteins
