Uses of Ammonia

Ammonia is the single most widely used compound in the fertilizer industry. It
is the starting material for the production of a various number of nitrogenous
fertilizers like ammonium phosphates, ammonium sulfate, ammonium nitrate
etc.
It is used directly or indirectly as the source for the production of
hexamethylenedeamine for the manufacture of nylon 6,6. In the manufacture of
rayon, ammonia is used in the preparation of ammoiacal copper hydroxide
soulutio for dissolving the copper linters. Oxidation of propylene with ammonia
gives acrylonitrile, used for the manufacture of acrylic fibres, resins, and
elastomers.
Hexamethylenetetramine, produced from ammonia and formaldehyde, is used
in the manufacture of phenolic thermosetting resins. Toluene 2,4 disocyanate
(TDI), employed in the production of polyurethane foam, indirectly consumes
ammonia because nitric acid is a raw material in the TDI manufacturing process.
Urea produced from ammonia is used in the manufacture of urea-formaldehyde
synthetic resins. Melamine is produced by polymerization of dicyandiamine and
high pressure high temperature pyrolysis of urea, in the presence of ammonia
Lesser known uses of Ammonia are
1. As a refrigerant in both compression and absorption systems
2. In the pulp and paper industry for the pulping of wood
3. As a corrosion inhibitor in petroleum refineries.
4. In rubber production for the stabilization of natural and synthetic latex to
prevent coagulaion.
5. In the food and beverage industry as a source of nitrogen required for the
growth of yeast and micro-organism
6. As a curing agent in tanning industries.
