Abstract:

 On the theoretical basis of thermokinetics, a thermokinetic research method for simple order reactions - Characteristic time method has been proposed in this paper. The method only needs characteristic data of thermoanalytic curve tm, m. and A, and uses data processing on computer to give rate constant. In order to test the validity of this method, the saponificaion of ethyl butyrate and ethyl benzoate in aqueous ethanol solvent and the formation of hexamethylene tetramine in aqueous solution have been studied. The rate constants calculated with this method are in agreement with those in the literatures , and therefore, the characteristic time method for simple order reactions is believed to be correct.

Key words: Themokinetics, Themokinetic research method, Characteristic time method, Simple order reaction
