【Abstract】 On the theoretical basis of thermokinetics, a thermdeinetic research methed for simple order reactions - Characteristic time methed has been proposed in this pape.The method only ed characteristic data of thermoanalytic curve tm, m. and A, and uses data processing on compuer to give rate constant. In order to test the validity of thes methed,the saponificaion of ethyt butyrate and ethyt benzoate in aqueous ethanol solven and the fonnation 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 crder reactions is beieved to be correct.更多还原
