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.
Ammonia is a chemical comprising of nitrogen and hydrogen. It is designated in chemical notation as NH3. Ammonia is extremely soluble in water and is frequently used as a water solution called aqua ammonia. Ammonia chemically combines with water to form Ammonium hydroxide.
Anhydrous ammonia which is essentially pure (over 99 percent) ammonia. "Anhydrous" is a Greek word meaning "without water;" therefore, anhydrous ammonia is ammonia without water. Refrigerant grade anhydrous ammonia is a clear, colorless liquid or gas, free from visible impurities. It is at least 99.95 percent pure ammonia. Water content be above 33 parts per million (ppm) and oil cannot have a content above 2 ppm. Preserving the purity of the ammonia is essential to ensure proper function of the refrigeration system.

An agent for complexation, EDTA is mainly used for water treatment, as an additive to detergent, a chemical for photography, paper-making and oil-field. It is also used as detergent for boiler cleaning and reagent in chemical analysis.
1. High molecular chemical industry: EDTA is used as polymetization activator for butyl bezene latex, and polyreaction terminator in acrylic fibre production.
2.Daily chemicals: EDTA is used as additive to detergent, skin cream and hair-conditioner.
3.Paper-making: EDTA is used for treating the steamed fibre. It will promote the whiteness of paper and reduce the incrustation in the steamer.
4.Pharmaceutical industry: Through cyclopolymerization with methyl amide, EDTA is made into ethyl amide, a remedy for psoriasis. It is also a stablizer for some vaccines and an antihaemoagglutinin.
5. Textile dyeing and printing: EDTA will promote colour ability of the dyestuff and brightness of the dyed fabric.
