The thermal dynamics has its advantages in system that common method such as spectrometry, electrical etc. can not study, but because of the limitations of the existing Thermokinetic Research Methods such as Bell-Clunie Research Method, Borchardt-Daniels Research Method, Dimensionless Parameter Method, Reduced Parameter Method, Analog Thermogram Method, Characteristic Parameter Method, Time Variable Method, Self-Function Regression Method, Reaction Dynamic Method of Thermal Conductivity Calorimeter is established that has a wide scope of application (some reactions that not too fast such as polymerization, some non-homogeneous reactions such as Micelle catalytic etc.) and high accuracy. Deriving several dynamics of the equations suit to common non-reversible reaction and establishing new method to resolve first order reaction and second order reaction according to thermokinetic basic theory were this article's purpose. The accuracy of this method was verified by studying ethyl acetate saponification reaction and sucrose hydrolysis reaction systems. This new thermal dynamic method can make use of diagrams for the reaction rate constant and related thermal dynamic parameters such as the activation energy and accuracy must be high.This paper studied the thermal dynamics of micellar catalytic cinnamaldehyde hydrolysis using the thermal conductivity of heat-Kinetics. The reaction rate constant and the activation energy was calculated through thermal spectrum curve of cinnamaldehyde hydrolysis reaction.
