| Abstract | ||
| The reaction was carried out as psedo first order reaction for the first time for permanganate and the second one for cinnamaldehyde. Reaction order was calculated at different concentration and temperature for both reactants. The results revealed that the reaction followed first order reaction. The reaction speed depend on the concentration of both cinnamaldehyde and permanganate. The reaction was followed by IR spectroscopy. The oxidation of aldehyde to carboxylate proceed through C=O (using IR). The spectra of the oxidation of product and authentic acid was measured and found to be almost similar. Thermodynamic values of activation for the reaction were measured at different temperature (288-323 oK). In addition the effect of ionic strength through NaCl adding was studied which showed a certain effect observed at high concentration. The value of reaction constant were changed in at high concentration of the added salt and the logarithm value of the reaction constant changed linearly with the ionic strength of the solution. | ||
