Ammonium Sulfate

Ammonium sulfate is an inorganic substance, colorless crystals or white granules, odorless.℃The above decomposition. Solubility in water: 0℃70.6g, 100℃103.8 g. Insoluble Ethanol and acetone 。0.1Moore/Large aqueous solutionpH5.5. Relative density 1.77. Refractive index 1.521. Ammonium sulfate is mainly used as fertilizer and is suitable for various soils.andCrops. It can also be used in textiles, leather, medicine and other fields.

use:

An excellent nitrogen fertilizer (commonly known as fertilizer powder), suitable for general soil and crops, can make branches and leaves grow vigorously, improve fruit quality and yield, enhance crop resistance to disasters, and can be used as base fertilizer, topdressing and seed fertilizer. It can react with salt to produce ammonium chloride, react with aluminum sulfate to produce ammonium alum, and make refractory materials with boric acid. Adding it to the electroplating solution can increase conductivity. It is also a catalyst for food color, a nitrogen source for culturing yeast in fresh yeast production, an auxiliary dye for acid dyeing, and a leather deashing agent. In addition, it is also used in beer brewing, chemical reagents and battery production. Another important function is to mine rare earths. Ammonium sulfate is used as the raw material for mining. The rare earth elements in the ore are exchanged in the form of ion exchange. The leaching solution is collected, impurities are removed, precipitated, pressed, and burned to form rare earth ore. About 5 tons of ammonium sulfate are required for every ton of rare earth ore produced. There are many biological uses, mostly in protein purification processes, because ammonium sulfate is an inert substance and is not easy to react with other biologically active substances. It can protect protein activity to the greatest extent during the purification process. In addition, ammonium sulfate is extremely soluble and can form a high-salt environment to prepare for protein precipitation and subsequent high-salt purification.℃With normal temperature 25℃The solubility is quite different. The following is the molar concentration of ammonium sulfate at different saturations at two temperatures.
