Industrial Anhydrous Ammonia NH3 Fertilizer Packaged In ISO Tank
A saturated solution of ammonium nitrate contains 0.83 mol solute per mole of ammonia and has avapour pressure of less than 1 bar even at 25 °C (77 °F).flammable gas
Liquid ammonia will dissolve the alkali metals and other electropositive metals such as magnesium, calcium, strontium, barium, europium andytterbium. At low concentrations (<0.06 mol/l), deep blue solutions are formed: these contain metal cations and solvated electrons, free electrons that are surrounded by a cage of ammonia molecules.
These solutions are very useful as strong reducing agents. At higher concentrations, the solutions are metallic in appearance and in electrical conductivity. At low temperatures, the two types of solution can coexist as immiscible phases.
The range of thermodynamic stability of liquid ammonia solutions is very narrow, as the potential for oxidation to dinitrogen, E° (N2 + 6NH4+ + 6e− ⇌ 8NH3), is only +0.04 V. In practice, both oxidation to dinitrogen and reduction to dihydrogen are slow.
This is particularly true of reducing solutions: the solutions of the alkali metals mentioned above are stable for several days, slowly decomposing to the metal amide and dihydrogen. Most studies involving liquid ammonia solutions are done in reducing conditions; although oxidation of liquid ammonia is usually slow, there is still a risk of explosion, particularly if transition metal ions are present as possible catalysts.

2. Typical technical data (COA)
|High Grade||First Class|
|Oil mg/kg ≤||5||1.6|
|Fe mg/kg ≤||1||0.7|
|Cylinder Size||Filling Weight (kg)||
|Fertilizer||Globally, approximately 88% of ammonia is used as fertilizers
either as its salts, solutions or anhydrously. When applied to soil, it helps provide increased yields of crops such as maize and wheat
|Precursor to nitrogenous compounds||Ammonia is directly or indirectly the precursor to most nitrogen-containing compounds|
|Cleaner||Household ammonia is a solution of NH3 in water used as a general purpose cleaner for many surfaces|
|Fermentation||Solutions of ammonia ranging from 16% to 25% are used in the fermentation industry as a source of nitrogen for microorganisms and to adjust pH during fermentation|
|Antimicrobial agent for food products||Anhydrous ammonia is currently used commercially to reduce or eliminate microbial contamination of beef|
Because of ammonia's vaporization properties, it is a useful refrigerant. It was commonly used prior to the popularisation of chlorofluorocarbons (s). Anhydrous ammonia is widely used in industrial refrigeration applications and hockey rinks because of its high energy
efficiency and low cost
|For remediation of gaseous emissions||
Ammonia is used to scrub SO2 from the burning of fossil fuels, and the resulting product is converted to ammonium sulfate for use as fertilizer.
8.As a fuel - The raw energy density of liquid ammonia is 11.5 MJ/L,which is about a third that of diesel
|As a stimulant||Ammonia, as the vapor released by smelling salts, has found significant use as a respiratory stimulant. Ammonia is commonly used in the illegal manufacture of methamphetamine through a Birch reduction|
|Textile||Liquid ammonia is used for treatment of cotton materials, giving properties like mercerisation, using alkalis. In particular, it is used for prewashing of wool|
|Lifting gas||At standard temperature and pressure, ammonia is less dense than atmosphere, and has approximately 60% of the lifting power of hydrogen or helium. Ammonia has sometimes been used to fill weather balloons as a lifting gas|
|Woodworking||Ammonia has been used to darken quartersawn white oak in Arts & Crafts and Mission-style furniture. Ammonia fumes react with the natural tannins in the wood and cause it to change colours|
