"amine" refers to organic amine, such as: CH3CH2NH2 ethylamine, C6H5NH2 aniline, (CH3)3N trimethylamine, etc. Wherein the n atom is attached to a hydrocarbon group;
"Ammonium" is used for quaternary ammonium salt or quaternary ammonium group, where N atom is connected with 4 atoms or groups; For example, ammonium chloride NH4Cl, (CH3) 3NCHC3OH trimethyl ethyl ammonium hydroxide and so on. Quaternary ammonium cation with "ammonium"
Ammonia (ammonia), or "ammonia gas", is a compound of nitrogen and hydrogen with the molecular formula NH? It is a colorless gas with a strong pungent smell.
It is very soluble in water. At normal temperature and pressure, 1 volume of water can dissolve 700 times the volume of ammonia, and the aqueous solution is also called ammonia water. Cooling and pressurizing can become liquid, and liquid ammonia is refrigerant. Ammonia is also an important raw material for manufacturing nitric acid, fertilizers and explosives. Ammonia is very important to life on earth. It is an important component of many foods and fertilizers.
Ammonia is also a direct or indirect component of all drugs. Ammonia has a wide range of uses, and it also has corrosive and other dangerous characteristics. Because of its wide use, ammonia is one of the largest inorganic compounds in the world, and more than 80% of ammonia is used to make chemical fertilizers. Because ammonia can provide lone pair, it is also a Lewis base.
