Amine. In chemistry, amines (/ ə ˈ m iː n, ˈ æ m iː n /, [1] [2] UK also / ˈ eɪ m iː n / [3]) are compounds and functional groups that contain a basic nitrogen atom with a lone pair.Formally, amines are derivatives of ammonia (NH 3), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group [4] (these may respectively be called alkylamines ...
This colorless liquid is one of the isomeric amines of hexane. At standard temperature and pressure, it has the ammonia/bleach odor common to amines and is soluble in almost all organic solvents. Applications
Niacin, essential to many types of life, is an example of a heterocyclic amine.. Heterocyclic amines, also sometimes referred to as HCAs, are chemical compounds containing at least one heterocyclic ring, which by definition has atoms of at least two different elements, as well as at least one amine (nitrogen-containing) group.
Aniline (from Portuguese anil 'indigo shrub', and -ine indicating a derived substance) [6] is an organic compound with the formula C 6 H 5 NH 2.Consisting of a phenyl group (−C 6 H 5) attached to an amino group (−NH 2), aniline is the simplest aromatic amine.
Since August 2012, the new standard EN 14362-1:2012 Textiles - Methods for determination of certain aromatic amines derived from azo colorants - Part 1: Detection of the use of certain azo colorants accessible with and without extracting the fibres is effective. It had been officially approved by the European Committee for Standardization (CEN ...
Like other simple aliphatic amines, ethylamine is a weak base: the pK a of [CH 3 CH 2 NH 3] + has been determined to be 10.8 [8] [9] Ethylamine undergoes the reactions anticipated for a primary alkyl amine, such as acylation and protonation. Reaction with sulfuryl chloride followed by oxidation of the sulfonamide give diethyldiazene, EtN=NEt. [10]

2-Aminoalcohols are an important class of organic compounds that are often generated by the reaction of amines with epoxides: C 2 H 4 O + R−NH 2 → RNHC 2 H 4 OH. Simple alkanolamines are used as solvents, synthetic intermediates, and high-boiling bases. [2] Hydrogenation or hydride reduction of amino acids gives the corresponding 2 ...
