摘要
报道了一种以ＮａＢｒＯ３为氧化剂，丙酮酸（Ｐｙｒ）为有机底物，［ＮｉＤＴＨ］（ＣｌＯ４）２（其中ＤＴＨ为１２，１４二甲基１，４，８，１１四氮杂环十四１１，１４二烯）为催化剂，稀Ｈ２ＳＯ４为介质的化学振荡反应新体系．对该体系的振荡特性进行了实验描述，测定了该体系发生振荡的组分浓度范围、振荡轨迹，研究了各物种浓度、自由基抑制剂、还原性物质及Ａｇ＋、Ｈｇ２＋等离子对振荡的影响，并对其反应机理作了初步探讨．
The chemical oscillating reaction is investigated of NaBrO3Pyr(ClO4)2-H2SO4 system, where (ClO4)2 is [Ni(Me)211,14diene N4] (ClO4)2. The features of the oscillations are described in detail. The domains of the existence of the oscillation are determined and the effects of catalyst, reductants, radical inhibitors, Ag+ and temperature on the oscillations are studied.
