Amine is a class of organic compound containing at least one N atom. In other words, amine can be regarded as substituted product of ammonia gas in which one or multiple hydrogen atoms are replaced by hydrocarbons. Based on the types of hydroxyl groups attached to N atoms, amine can be divided into fatty amines and aromatic amines. Lower fatty amines possess large solubility which can be attributed to the formation of hydrogen bond between amine molecule and water. Similar to ammonia, amine show alkalinity due to the unshared pairs of electrons of N atom.
