Ammonia Chemical Properties,Usage,Production

Ammonia (chemical formula: NH3) is a compound of nitrogen and hydrogen. As a colorless pungent gas, it is highly soluble in water to become the liquid ammonia. It is also one of the most abundant nitrogen-containing compound in the atmosphere. It provides the fundamental nutrients demands for various kinds of organisms by serving as a precursor of their food and fertilizer. It is also important for various kinds of biological processes. In addition, it serves as a building blocks of many kinds of commercially important nitrogen compounds as well as pharmaceutical products. The major application of ammonia is acting as the fertilizer to supply the nitrogen source of plants and animals. It is used in the manufacture of commercial explosive such as TNT. It is applied to textile industry for the manufacture of nylon and rayon, the dyeing and scouring of cotton and silk as well as being used as a catalyst in the production of some synthetic resins. It also has applications in various metallurgical processes and fermentation processes. It can even be used as a cleaner and antimicrobial reagent in the food. Finally, it is also an important routine reagent used in lab. For example, liquid ammonia is a common solvent in the lab. In current days, ammonia is produced by the Haber-Bosch process which has industrial hydrogen be reacted with atmospheric nitrogen under high temperature and pressure in the presence of catalyst. For small-scale lab synthesis, ammonia can also be manufactured through the heating of urea and Ca (OH)2. Low concentration of ammonia has no significant effect on human beings. However, exposure to high concentration of gaseous ammonia can result in lung damage and even death, thus protective measures should be taken during the operation.

Air & Water Reactions
Soluble in water with evolution of heat. The amount of heat generated may be large.
Reactivity Profile
AMMONIA is a base. Reacts exothermically with all acids. Violent reactions are possible. Readily combines with silver oxide or mercury to form compounds that explode on contact with halogens. When in contact with chlorates Ammonia forms explosive ammonium chlorate [Kirk-Othmer, 3rd ed., Vol. 2, 1978, p. 470]. Reacts violently or produces explosive products with fluorine, chlorine, bromine and iodine and some of the interhalogen compounds (bromine pentafluoride, chlorine trifluoride). Mixing of bleaching powder (hypochlorite solution) with ammonia solutions produces toxic/explosive ammonia trichloride vapors. Undergoes potentially violent or explosive reactions on contact with 1,2-dichloroethane (with liquid ammonia), boron halides, ethylene oxide (polymerization), perchlorates or strong oxidants (chromyl chloride, chromium trioxide, chromic acid, nitric acid, hydrogen peroxide, chlorates, fluorine, nitrogen oxide, liquid oxygen). Reacts with silver chloride, silver oxide, silver nitrate or silver azide to form the explosive silver nitride. May react with some heavy metal compounds (mercury, gold(III) chloride) to produce materials that may explode when dry. [Bretherick, 5th ed., 1995, p. 1553].
Health Hazard
Vapors cause irritation of eyes and respiratory tract. Liquid will burn skin and eyes. Poisonous; may be fatal if inhaled. Contact may cause burns to skin and eyes. Contact with liquid may cause frostbite.
Fire Hazard
Mixing of ammonia with several chemicals can cause severe fire hazards and/or explosions. Ammonia in container may explode in heat of fire. Incompatible with many materials including silver and gold salts, halogens, alkali metals, nitrogen trichloride, potassium chlorate, chromyl chloride, oxygen halides, acid vapors, azides, ethylene oxide, picric acid and many other chemicals. Mixing with other chemicals and water. Hazardous polymerization may not occur.
