Anhydrous ammonia is widely used in industrial refrigeration applications and hockey rinks because of its high energy efficiency and low cost. It suffers from the disadvantage of toxicity, and requiring corrosion resistant components, which restricts its domestic and small-scale use.
The table above gives properties of the vapor–liquid equilibrium of anhydrous ammonia at various temperatures. The second column is vapor pressure in kPa. The third column is the density of the liquid phase. The fourth column is the density of the vapor.
For example, in Australia, anhydrous ammonia UN 1005 is classified as 2.3 (toxic gas) with subsidiary hazard 8 (corrosive), whereas in the U.S. it is only classified as 2.2 (non-flammable gas). [ 6 ] People who handle dangerous goods will often wear protective equipment, and metropolitan fire departments often have a response team specifically ...
The truck was carrying about 7,500 gallons of anhydrous ammonia at the time, according to the Illinois Environmental Protection Agency. The agency said early estimates indicate more than half ...
A father and two children were among five people who died in rural Illinois after a multi-vehicle accident sparked a spillage of anhydrous ammonia when the truck carrying the toxic substance ...
4. The water-absorbing nature of anhydrous ammonia that causes the greatest injury (especially to the eyes, nose, throat or lungs), and which can cause permanent damage. It is a colourless gas at atmospheric pressure and normal temperature, but under pressure readily changes into a liquid. Anhydrous ammonia has a high affinity for water.
Ammonia solution, also known as ammonia water, ammonium hydroxide, ammoniacal liquor, ammonia liquor, aqua ammonia, aqueous ammonia, or (inaccurately) ammonia, is a solution of ammonia in water. It can be denoted by the symbols NH 3 (aq). Although the name ammonium hydroxide suggests a salt with the composition [NH + 4][OH −
