The 2013-2017 Research and Investment Prospect Evaluation Report on China's Liquid Ammonia Industry states that liquid ammonia is mainly used for the production of nitric acid, urea, and other chemical fertilizers, and can also be used as a raw material for pharmaceuticals and pesticides. Liquid ammonia is used in the defense industry to manufacture propellants for rockets and missiles. It can be used as an ammonification raw material for organic chemical products and also as a refrigerant. Liquid ammonia can also be used for silk finishing of textiles. The lone electron pairs in NH3 molecules tend to form coordination bonds with other molecules or ions, generating various forms of ammonia complexes. Compounds such as [Ag (NH3) 2]+, [Cu (NH3) 4] 2+, BF3 · NH3, etc. are all coordinated with NH3. Liquid ammonia is a great solvent, and due to the polarity of its molecules and the presence of hydrogen bonds, it shares many physical properties with water. Some reactive metals can displace hydrogen and generate hydroxides from water, making it less likely to displace hydrogen in liquid ammonia. But liquid ammonia can dissolve metals to form a blue solution. This metal liquid ammonia solution can conduct electricity and slowly decompose to release hydrogen gas, with strong reducibility. For example, sodium liquid ammonia solution: The reason why metal liquid ammonia solution appears blue, can conduct electricity, and has strong reducibility is due to the generation of "ammonia electrons" in the solution. For example, when sodium metal dissolves in liquid ammonia, it loses its valence electrons and generates positive ions:

Heating liquid ammonia to 800-850 ℃, under the action of nickel based catalyst, ammonia can be decomposed to obtain a hydrogen nitrogen mixture gas containing 75% H2 and 25% N2. The gas produced by this method is a good protective gas that can be widely used in the semiconductor industry, metallurgical industry, as well as other industries and scientific research that require a protective atmosphere.

Ammonia gas and acetic acid gas are heated to 420 degrees Celsius, and acetonitrile is synthesized under the action of a catalyst.
