amine

(əmēn`, ăm`ēn): see under amino groupamino group,
in chemistry, functional group that consists of a nitrogen atom attached by single bonds to hydrogen atoms, alkyl groups, aryl groups, or a combination of these three. An organic compound that contains an amino group is called an amine.

amine

[ə′mēn]
(organic chemistry)
One of a class of organic compounds which can be considered to be derived from ammonia by replacement of one or more hydrogens by functional groups.

In acidic conditions the amine group of CH is protonated which causes electrostatic interactions of carboxylic group of OKG with protonated CH to produce a tight network which may lead to lower water uptake at lower pH.
In this figure there was a noticeable reduction in percentage removal at lower pH values which is mainly due to the protonation of the amine group that creates an electrostatic repulsion between the metal ions in solution and the amine group of chitosan.
The dye antenna is attached to the nanoparticle by reacting either a carboxylic acid, isothiocyanate or NHS ester group, on the dye with an amine group on the functionalized nanoparticle to form an amide bond.
The zeta potential of SA containing SLNs was lower than that of DDA ones (Figure 2), probably due to the reasons aforementioned already that SA has less ability to produce hydrogen bond with HA and consequently the more free amine groups imparting positive charge to the SLNs.
TGA experiments have shown that the PE-MCM-41 matrix itself is thermally stable up to 1000[degrees]C, whereas the decomposition of the grafted amine groups starts already at 200-250[degrees]C [24, 26,28].
1); Step 1: monoalkylation of the amine group; and Step 2: quaternization of the alkyl chitosan.
The presence of amine group is expected to interact with acidic groups on the carbon black surface, resulting in an increase in the pH of the medium, which is actually seen (table 6).
Last year, Payne and graduate student Wei-Qiang Sun began to harness the reactivity of chitosan's amine group to help streamline chemical manufacturing.
Compatibilizers containing an amine group (am, sam, bsa) had different impacts on mechanical and rheological properties of SIL/EP systems.
However, all these routes were involving the synthesis of the primary amine group through protection and deprotection.
reported that the grafting was achieved through a reaction between an amine group of DETA with an epoxy group of PGMA and the adsorbent showed excellent adsorption performance for copper ions at solution pH greater than 3.
