ammonia, chemical formula NH3, is a colorless, strong pungent odor of gas, easily soluble in water. It is an important basic chemical raw material, widely used in agriculture, industry and energy fields. In agriculture, synthetic ammonia is the main raw material for the manufacture of nitrogen fertilizer, such as urea, ammonium bicarbonate, etc., which is of great significance for increasing crop yields; in industry, synthetic ammonia is used to produce nitric acid, ammonium salt, melamine and other chemical products. It is widely used in explosives, dyes, plastics, medicine and other industries; in addition, synthetic ammonia is also used as a hydrogen source, It plays an important role in fuel cells and some chemical synthesis processes. As a key chemical raw material, synthetic ammonia plays an important role in the national economy.
(1) Synthetic ammonia is mainly used as a raw material for the production of nitrogen fertilizers in the agricultural field, such as urea, ammonium nitrate, ammonium sulfate, etc. These nitrogen fertilizers can effectively improve soil fertility and promote crop growth, which is an important guarantee for agricultural production. According to statistics, about 80% of ammonia is used in the production of chemical fertilizers.
(2) In the chemical industry, synthetic ammonia is an important raw material for the production of nitric acid, nitrate, explosives, dyes and other chemical products. Nitric acid is produced by ammonia oxidation and is widely used in the production of fertilizers, explosives and pharmaceuticals. In addition, ammonia is also used in the manufacture of trinitrotoluene, nitroglycerin, nitrocellulose and other materials needed by the defense industry.
(3) Due to the high thermal conductivity and low boiling point of ammonia, liquid ammonia is also widely used in industrial refrigeration systems, such as food refrigeration and air conditioning systems, and is an effective refrigerant.
(4) Ammonia has also received increasing attention as a potential clean energy carrier. It can be used as a storage and transportation medium for hydrogen, because the storage and transportation of ammonia is easier and safer than hydrogen. It has great application prospects in the field of energy.
