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(NH 3 (in which the bond angle between the nitrogen and hydrogen is 107°), wherein one or more hydrogen atoms have been replaced by a substituent such as an ...
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 ...
Isopropylamine can be obtained by reaction of isopropyl alcohol with ammonia in presence of a catalyst: [3] (CH 3) 2 CHOH + NH 3 → (CH 3) 2 CHNH 2 + H 2 O. Isopropylamine is a building block for the preparation of many herbicides and pesticides including atrazine, bentazon, glyphosate, imazapyr, ametryne, desmetryn, prometryn, pramitol, dipropetryn, propazine, fenamiphos, and iprodione.

Or by the reaction of allyl chloride with hexamine. [4] Pure samples can be prepared by hydrolysis of allyl isothiocyanate. [5] It behaves as a typical amine. [6] Polymerization can be used to prepare the homopolymer (polyallylamine) or copolymers. The polymers are promising membranes for use in reverse osmosis. [3]
