| Abstract The paper deals with kinetic data of Beckmann rearrangement of substituted anti benzaldoxime to substituted benzoic acid and ammonia by action of perchloric acid in 10% ethanol by volume . A spectrophotometric method was used for this investigation , by following the decay absorbances of benzaldoximes at the proper analytical wavelengths . The reaction was found to obey a pseudo first order kinetic with respect to oxime . The observed rate constants k were evaluated in the temperature in the range 323-353 K and found to depend on temperature and donor or acceptor property of the substituent as well as its position on the aromatic rings . Finally the activation parameters for Beckmann rearrangement reactions were calculated and discussed . | ||
