| Abstract: | In this paper, a new type of chemical oscillatory reaction system: CH3CHOHCOOH-CH3COCH3-BrO3^--Mn^2^+-H2SO4 was reported. The initial concentration of each reactant and the affect factor were investigated, the activation parameter of inductory phase EIN, oscillatory period EP, oscillatory life EL were obtained, EIN=60.68kJ.mol^-^1, EP=61.03kJ.mol^-^1, EL=135.80kJ.mol^-^1. The new characteristics of inductory phase and the possible mechanism of oscillatory reaction were analyzed. |
