系统地研究了反应物、催化剂以及温度对封闭体系BZ振荡反应的影响,振荡反应的最佳初始条件为:[H2SO4]=0.8mol/L,[CH2(COOH)2]=0.175mol/L,[KBrO3]=0.06mol/L,0.004mol/LCe(SO4)2,温度为303K.振荡周期与主要反应物浓度之间的动力学方程:Tp=kC-0.635KBrO3×C-0.478CH2(COOH)2×C-0.505H2SO4.一般说来,主要反应物浓度对振荡反应参数影响不大,但催化剂铈的浓度变化对振荡反应参数有明显影响.
The optimal initial conditions for the oscillatory reaction were as follows: [H2SO4] = 0.8mol / L, [CH2 (COOH) 2] = 0.175mol / L, the reaction temperature and the reaction temperature were investigated systematically. [KBrO3] = 0.06 mol / L, 0.004 mol / L Ce (SO4) 2 at a temperature of 303 K. The kinetic equation between the oscillation period and the concentration of the main reactants is: Tp = kC-0.635 KBrO3 x C-0.478 CH2 (COOH) 2 × C-0.505H2SO4. In general, the concentration of the main reactant has little effect on the parameters of the oscillation reaction, but the change of the concentration of the catalyst cerium has a significant effect on the parameters of the oscillation reaction.
