| 摘 要： | 本文报道了一种以四氮杂大环四烯镍(Ⅱ)配合物Ni(TIM)](ClO4)2为催化剂,柠檬酸为有机底物的硫酸环境的新型的B-Z振荡反应体系。讨论了不同浓度的溴酸钠、硫酸、柠檬酸对振荡周期(tp)、振幅(A)、振荡次数(n)的影响,发现振荡周期tp与溴酸钠、硫酸、柠檬酸的浓度有关,关系表达式:tp(s)∝C0-2.003(NaBrO3)C0-2.881(H2SO4)C0-3.16(Citric acid)。研究了各种还原剂、自由基抑制剂、Ag+、Hg2+对该振荡反应的不同程度的影响。最后提出了该反应的反应机理。

| Abstract: | In this paper,a new B-Z oscillating reaction in which a tetramethyl tetraazacyclotetradeca-tetraene(TIM) Nickel(Ⅱ)complex Ni(TIM)](ClO4)2 serves as catalyst and Citric acid as organic substrate in aqueous H2SO4 is reported.The experimental results have shown that the different concentrations of NaBrO3,H2SO4 and Citric acid have effects on the oscillation period(tp),the amplitude of oscillation(A),and the oscillating cycles(n).It is found that the oscillation period(tp) is dependent on the initial concentrations of NaBrO3,H2SO4 and Citric acid.The oscillation period tp can be expressed as: tp(s)∝C0-2.003(NaBrO3)C0-2.881(H2SO4)C0-3.16(Citric acid).The effect of some reducing agent,free radicals,Ag+,Hg2+ on the oscillation is also studied.A tentative mechanism based on the FKN is proposed latter. |
