以山梨醇、甘露醇为底物的化学振荡的研究

OSCILLATIONS IN B-Z REACTIONS OF MANNITOL SYSTEM AND SORBITOL SYSTEM

报道了以山梨醇 (简称SO)、甘露醇 (简称MO)为底物的化学振荡的特点 ,而且通过对山梨醇、甘露醇、葡萄糖 (简称Glu)为底物的 3种振荡的比较 ,研究了几个体系的振荡行为 ,得到了它们的振荡动力学参数 ,根据底物结构的不同及FKN机理 ,对实验结果进行了讨论 .认为物质的结构影响振荡行为 ,Br-的浓度是产生tp1振荡的关键 .

The new oscillating systems of Mannitol(MO)-KBrO 3-Acetone(Act)-H 2SO 4-MnSO 4 and Sorbitol(SO)-KBrO 3-Acetone(Act)-H 2SO 4-MnSO 4 were reported.We studied the behavior of Mannitol system and Sorbitol system and the oscillatory kinetic parameters were obtained.Comparing Mannitol system,Sorbitol system and Glucose system with each other,we analyzed the experimental results according to different structure of reactants and FKN mechanism.We consider that the oscillatory action is affected by the structure of material and the density of Br - is the crux of producing the oscillation of tp 1.
