Synthesis, spectroscopic and Kinetic studies of some N-aryl pyridinium derivatives
Keywords:
N- phenylpyridinium, reaction kinetics, conductivity and spectroscopy methodsAbstract
New N- phenylpyridinium derivatives compounds were synthesized, their molecule structure were confirmed by elemental analyses, IR, NMR and UV-visible spectroscopy. The reaction kinetics of these compounds with metal ions such as Fe2+, Cu2+and V3+ were investigated by conductivity and spectroscopy methods respectively at different time and different temperature. From spectroscopy and conductivity studies of N-phenylpyridinium compounds under investigation we found the values of activation energy for all compounds in conductometric methods(1.7-9.2 kJmol-1) are smaller than the corresponding values measured by spectroscopy method (2.2-13.5 kJ mol-1), therefore we can conclude that the conductometric methods is better than spectroscopy method for studying kinetic reaction for these compounds.
