Abstract: On the foundation of experimental results of thermokinetics, a general analogthermogramequation,△=αte^-kβt,which can simulate the thermograms of chemical reactionswith simple order,has been proposed in this paper.Combined with the basic theory ofthermokinetics,a novel studying method of thermokinetics, the analog thermogram method,has been developed.The formulae for calculating kinetic parameter K_n and rate constant k_n,which do not involve any instrument constants, have been derived.The expression of thecooling constant of thermokinetic system has been obtained at the same time.The analogthermogram method can be applied not only to studying slow chemical reactions, but also tostudying faster ones.In order to test the validity of this method, the saponifications of ethylpropionate and ethyl benzoate in aqueous ethanol solvent, the saponification of ethyl butyrate in aqueous solution, the substitution of benzyl chloride in aqueous DMSOsolvent, theformation of hexamethylenetetramine in aqueous solution, and the polymerization of acrylamide have been studied.The rate constants calculated with this method are in agreementwith those in the literatures, and therefore the analog thermogram method is believed to be Correct.
