Ammonium sulfate

CAS RN: 7783-20-2

Major Uses

For ammonium sulfate (USEPA/OPP Pesticide Code: 005601) ACTIVE products with label matches. /SRP: Registered for use in the USA but approved pesticide uses may change periodically and so federal, state and local authorities must be consulted for currently approved uses./
Various ... uses include applications as: cattle feed; in cellulose insulation; in the chemical industry (for the production of persulfates); for the production of fire extinguisher powder and flame proofing agents; in the production of metals (e.g. chromium), and noble metals (e.g. gold), and as a flotation auxiliary in the treatment of ores; in the woodworking industry for the production of curing agents for urea-formaldehyde and melamine-formaldehyde resins used in the manufacture of chipboard; in the pharmaceutical industry as a nutrient for microorganisms; in the textile industry as an additive to dye baths, wadding and wicks, and in the production of auxiliaries for textiles processing; in the wood pulp industry in the production of yeast and sulfite liquor. Further uses reported in the literature include in shale stabilization and drilling fluids, and for analytical purposes. It is also used in the manufacturing of ammonia alum, and hydrogen sulfide, wash- and cleaning agents and disinfectants.
Manufacture of ammonia alum; in the manufacture of H2SO4 to free it from nitrogen oxides; analytical uses; freezing mixtures, flameproofing fabrics and paper; manufacture of viscose silk; tanning, galvanizing iron; in fractionation of proteins; as fertilizer.
Fertilizers, water treatment, fermentation, fireproofing compositions, viscose rayon, food additive.
... fertilizer; for this purpose it is valued both for its nitrogen content and for its readily available sulfur content
Adjuvant: water conditioning agent. Used with herbicides.
Ammonium sulfate has been identified as being used in hydraulic fracturing as a breaker. /From table/
Both oil base and water base fracturing fluids are being used in the fracturing industry. Water base, which includes alcohol-water mixtures and low strength acids, make up the majority of treating fluids. The common chemicals added to these fluids are polymers for viscosity development, crosslinkers for viscosity enhancement, pH control chemicals, gel breakers for polymer degradation following the treatment, surfactants, clay stabilizers, alcohol, bactericides, fluid loss additives and friction reducer. /Hydraulic fracturing/
