When mixed with oxygen, it burns with a pale yellowish-green flame. At high temperature and in the presence of a suitable catalyst, ammonia is decomposed into its constituent elements. Ignition occurs when chlorine is passed into ammonia, forming nitrogen and hydrogen chloride; if chlorine is present in excess, then the highly explosive nitrogen trichloride (NCl3) is also formed.
In organic chemistry, ammonia can act as a nucleophile in substitution reactions. Amines can be formed by the reaction of ammonia with alkyl halides, although the resulting -NH2 group is also nucleophilic and secondary and tertiary amines are often formed as byproducts.
An excess of ammonia helps minimise multiple substitution, and neutralises the hydrogen halide formed. Methylamine is prepared commercially by the reaction of ammonia with chloromethane, and the reaction of ammonia with 2-bromopropanoic acid has been used to prepare racemic alanine in 70% yield. Ethanolamine is prepared by a ring-opening reaction with ethylene oxide: the reaction is sometimes allowed to go further to produce diethanolamine and triethanolamine.
Amides can be prepared by the reaction of ammonia with carboxylic acid derivatives. Acyl chlorides are the most reactive, but the ammonia must be present in at least a twofold excess to neutralise the hydrogen chloride formed. Esters and anhydrides also react with ammonia to form amides. Ammonium salts of carboxylic acids can be dehydrated to amides so long as there are no thermally sensitive groups present: temperatures of 150–200 °C are required.
1. Physical properties
|Hazardous class for transort||2.3|
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|
