摘要
A new chemical oscillating reaction system:Diacetone\|BrO - 3\|Mn 2+ \|H 2SO 4 has been described.The best reaction condition and the reactant's concentrations have been reported. The effect of the reaction temperature on the oscillation has been studied and the average activation energies of the reaction during the oscillation period Ep and the oscillatory life E L are obtained, E p=100.68 kJ·mol -1 , E L=48.05 kJ·mol -1 .The new characteristics of oscillation period have been investigated in detail. The intermediate and the end product of the oscillatory reaction is proposed and the possible mechanism have been analysed.
