Abstract |
: |
The purpose of the present thesis was directed towards the development of a simple, rapid and accurate spectrophotometric methods for determination of some aminopyridines, 2-aminopyridine (2AP) and 4-aminopyridine (4AP), which have many biological applications. These methods depend on the formation of proton transfer complexes with some proton donors as 2,6-dichloro-4-nitrophenol (DCNP) and 2,4-dinitrophenol (DNP). Also it depend on the formation of colored charg transfer complexes with some electron acceptors as chloranilic acid (CHA), 2,5-dihydroxybenzoquinone (DHBQ) and 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ). The quantitative and analytical parameters of the methods suggested that the developed spectrophotometric methods were accurate, fast and sensitivity for determination of 2AP and 4AP in good concentration range as suggested from Beer,s law plots. Also the solid proton transfer and charge transfer complexes between the two aminopyridines and the proton donor and electron acceptors were isolated and characterized using elemental analysis, FTIR and 1H NMR measurements. These measurements confirmed the formation of the complexes in different ratios. Also these measurements confirmed that, for the proton transfer complexes the interaction site is the hydroxyl group with the amino group or ring nitrogen. Also these measurements showed that the formed charge transfer complexes included proton transfer. |
