Amine is a type of compound that is derived from ammonia. In other words, amines are basically classified as functional groups or organic nitrogen compounds.
Thereby the higher order amines become relatively weaker bases in aqueous solution due to the limitations in hydrating their polar sites.doi:10.1016/0166-1280(89)87081-2P. NagyJournal of Molecular Structure THEOCHEMNagy P. Theoretical calculations on the basicity of amines. journal of molecular ...
The N(1s) binding energy, which decreases in the order NH > CHNH > (CH)NH > (CH)N, shows excellent agreement with -..delta..(PA) in these compounds. The calculated relaxation-energy (or polarization) contribution to ..delta..E/sub B/ for both alcohols and amines agrees very well ...
The chemical reactivity of a set of borophosphines of the general formula R2B-G-PY2, where G is the connector group between the Lewis acidic site, a borane group, and the Lewis basic site, a phosphine fragment, is theoretically investigated through their Lewis acidity and Lewis basicity, as...
The adsorption order at 25°C was: BA (0.9) > MA (0.72) > AN (0.63) > DPA (0.48) > GA (0.30 mmol/g), and the order at 80°C was BA > AN > GA ~ MA ~ DPA. Both the orders reflected the importance of basicity over hydrophobicity of amines in the adsorption onto charcoal. ...
The adsorption order at 25 degrees C was: BA (0.9)>MA (0.72)>AN (0.63)>DPA (0.48)>GA (0.30mmol/g), and the order at 80 degrees C was BA>AN>GA similar to MA similar to DPA. Both the orders reflected the importance of basicity over hydrophobicity of amines in the adsorption onto...
Comparisons with gas phase data show that the abnormal basicity order of the amines B in Me2SO is mainly due to the decreasing exothermicity of the heat of solution of the BH+ ions with the number of N鈥擧 protons available for H-bonding to Me2SO. The large increase in basicity ...

Both the orders reflected the importance of basicity over hydrophobicity of amines in the adsorption onto charcoal. The charcoal was characterized using FTIR, SEM, elemental analysis, Boehm titration, pH titration, and pH drift methods. The charcoal was found to have significant amount of carboxylic...
