Physical and Chemical Properties
Ammonium hydroxide, also called Aqua Ammonia, solution of ammonia gas in water, a common commercial form of ammonia. It is a colourless liquid with a strong characteristic odour. In concentrated form, ammonium hydroxide can cause burns on contact with the skin; ordinary household ammonia, used as a cleanser, is dilute ammonium hydroxide.
Application
1. Agricultural use: Diluted in agriculture, it can be used as fertilizer. The ammonia concentration of agricultural ammonia water is generally controlled within the range of 15% to 18% nitrogen content, and the carbonization degree is preferably greater than 100%. Fertilization is simple and there are many methods, such as ditch application, surface application, application with irrigation water or spraying.
2. Industrial use: Used in industries such as wool spinning, silk, printing and dyeing to wash wool, woolen fabric, grey fabric, dissolve and adjust pH, and as a dyeing aid. The organic industry is used as an aminating agent, a catalyst for the production of thermosetting phenolic resins, and the inorganic industry is used for the preparation of various iron salts.
3. In industry, it is used for large-scale integrated circuit decompression or plasma CVD to grow silica film as a pH regulator for boiler feedwater. Ammonia is used to neutralize carbon dioxide in feedwater, increase pH, and slow down the corrosion of carbon dioxide in feedwater. It is also a protective agent for boiler shutdown, and has a good protective effect on boilers that have a small amount of stored water that cannot be discharged.
4. In medicine, dilute ammonia water is used to stimulate respiration and circulation, treat fainting and fainting, and be used as a skin irritant and disinfectant.
5. Used as a detergent, neutralizer, and alkaloid leaching agent. It is also used in the pharmaceutical industry, gauze industry, printing, etc.
