What are the main uses of ammonia?

　　Ammonia can be used as base fertilizer or topdressing. The concentration of agricultural ammonia commonly used in China is 15%, 17% and 20% ammonia. The concentration of external agricultural ammonia is slightly higher, which is generally 25% ammonia (20% nitrogen). The total ammonia production of China in 2008 is less than 2.0%.

　　Laboratory use

　　Ammonia is an important reagent in the laboratory. It is mainly used as analytical reagent, neutralizer, alkaloid leaching agent, aluminum salt synthesis and weak alkaline solvent. It is used for the synthesis of aluminum salt and the verification and determination of some elements (such as copper and nickel), so as to precipitate the hydroxides of various elements.

　　Military use

　　As an alkaline disinfectant, it is used to disinfect sarin. Dilute ammonia water with 10% concentration (density 0.960) is commonly used, and the concentration in winter is 20%.

　　Industrial use

　　Wool spinning, silk, printing and dyeing and other industries are used to wash wool, woolen cloth and grey cloth, dissolve and adjust pH, and serve as dyeing aids. Organic industry is used as aminating agent and catalyst for the production of thermosetting phenolic resin, and inorganic industry is used for the preparation of various iron salts.

　　In industry, it is used for large-scale integrated circuit decompression or plasma CVD to grow silica film, boiler feed water pH regulator, and ammonia is used to neutralize carbonic acid in feed water, improve pH value and slow down the corrosion of carbon dioxide in feed water. It is also a protective agent for boiler shutdown. It also has good protective results for boilers with a small amount of water in the boiler that cannot be discharged.

　　In medicine, dilute ammonia is used to reflexively stimulate breathing and circulation, treat fainting and fainting, and make skin irritants and disinfectants.

　　As detergent, neutralizer and alkaloid extractant. It is also used in pharmaceutical industry, gauze mask industry, blueprint, etc.

　　Agricultural use

　　In agriculture, diluted ammonia can be used as chemical fertilizer. The ammonia concentration of agricultural ammonia is controlled within the range of 15% ~ 18% of nitrogen content, and the carbonation degree is greater than 100%. Fertilization is simple and has many methods, such as furrow application, surface application, application with irrigation water or spraying. When using, dilute it with water to less than 1000%, and avoid contacting with stems and leaves to avoid burns.

　　The application principle of ammonia is "no separation from soil and no separation from water". Not leaving the soil is to cover the soil deeply; Inseparable from water is to add water to dilute to reduce concentration, reduce volatilization, or combined with irrigation. As the density of ammonia water is smaller than that of water, attention should be paid to avoid burning plants due to excessive accumulation in local areas during irrigation.

　　Ammonia can be used as base fertilizer or topdressing. The concentration of agricultural ammonia commonly used in China is 15%, 17% and 20% ammonia. The concentration of external agricultural ammonia is slightly higher, which is generally 25% ammonia (20% nitrogen). In 2008, the output of ammonia was less than 0.2% of the total output of nitrogen fertilizer.
