By using these rat e constants, the activation energy of molecule was calculated as 17.6 K cal/mol. According to the changes of the reaction rat e constants with pH , it was concluded tha t the base-catalysed degradation of molecule was rathe r fast above pH 9.}, number={1}, publisher={Ankara University}
