Manufacturer Caprolactam Grade Fertilizer Ammonium Sulfate N21% Product Description
Product Description
 Ammonium sulfate (IUPAC-recommended spelling; also ammonium sulphate in British English), (NH4)2SO4, is an inorganic saltwith a number of commercial uses. The most common use is as a soil fertilizer. It contains 21% nitrogen and 24% sulfur.

Ammonium sulfate [(NH4)2SO4] was one of the first and most widely used nitrogen (N) fertilizers for crop production. It is now less commonly used, but especially valuable where both N and sulfur (S) are required. Its high solubility provides versatility for a number of agricultural applications.

Application:-

Used as materials for producing hydrogen peroxide, ammonia alum and ammonium chloride in chemical industry; flux in jointing industry; fireproof agent in textile industry; additive of plating bath in plating industry; nitrogenous in agricultural industry. Applicable to common soil and crops. Food-grade products are used as dough regulators and yeast nutrition.

Ammonium sulfate is used on a small scale in the preparation of other ammonium salts, especially ammonium persulfate.

A saturated solution of ammonium sulfate in heavy water (2H2O) is used as an external standard in sulfur (33S) NMR spectroscopywith shift value of 0 ppm.

Ammonium sulfate has also been used in flame retardant compositions acting much like diammonium phosphate. As a flame retardant, it lowers the combustion temperature of the material, decreases maximum weight loss rates, and causes an increase in the production of residue or char.
