Abstract |
: |
The purpose of the present thesis was directed towards the development of a simple, rapid and accurate spectorophotometric methods for determination of some aminopyridines, [2-amino-4-methylpyridine (2AMP), 2,6-diaminopyridine (2,6DAP) and 2,3-diaminopyridine (2,3DAP)]. These methods depend on the formation of proton transfer complexes with the proton donor 2,6 –dichloro -4-nitrophenol (DCNP) and charge transfer complexes with chloroanilic acid (CHA) in different solvents.
The quantitative and analytical parameter of the methods suggested that the developed spectrophotometric method was fast, accurate and sensitive for determination of
[2-amino-4-methylpyridine (2AMP), 2,6-diaminopyridine (2,6DAP) and
2,3-diaminopyridine (2,3DAP)] in good concentration range as suggested from Beer,s law plots. In addition, the solid proton transfer and charge transfer complexes between aminopyridines and proton donor and electron acceptor were isolated and characterized using elemental analysis, Fourier Transform Infrared Spectrophotometer (FTIR) and Nuclear Magnetic Resonance ( 1H NMR) measurements. These measurements confirmed the formation of the complexes in different ratios and the charge transfer complexes included also proton transfer. |
