This work deals with kinetic data of Beckmann rearrangement reaction of methyl 3 and 4- pyridyl ketoximes (No.1and 2) to the corresponding 3- pyridine and 4-pyridine carboxylic acid and methyl amine by action of perchloric acid as a catalyst. A spectrometric method was used in this investigation by following the decay of absorbances of ketoximes at optimal wavelengths. These reaction were obey pseudo first order kinetic with respect to ketoximes. Rate constants for these ketoximes were evaluated in the temperature range (298-338) k and found to depend on temperature , structure of ketoxime and the concentration of acid catalyst employed. Finally, the activation parameters for Beckmann rearrangement reaction of ketoximes were calculated ,interpreted and discussed.
