ANALOG THERMOGRAM METHOD .2. STUDIES ON T HERMOKINETICS OF IRREVERSIBLE CONSECUTIVE FIRST-ORDER REACTIONS

Based on our previous article, the research method of analog thermogra m method for consecutive first-order reactions has been proposed in th is paper. The rate constants of the consecutive first-order reactions can be obtained from the thermogram of conduction calorimeter with thi s method without using any apparatus constants. In order to test the v alidity of this method, the saponifications of diethyl phthalate and d iethyl succinate in aqueous ethanol solvent have been studied. The rat e constants calculated with this method are in agreement with those in literatures, and therefore, the analog thermogram method for consecut ive first-order reactions is believed to be correct.
