Abstract: By analyzing the physical model of flowing system, the relationship between heat power and flow rate was deduced, in which the sample was input by flow-mixed method with LKB 2277 Bioactivity Monitor. By using linear analysis method, reaction enthalpy and rate constant can be calculated simultaneously. This method was applied to ethyl acetate saponification reaction, and a significant result was obtained.

Key words: Thermokinetics, Second-order reaction, Flow-mixed method
