在金属离子(指常见的ce~(3+)、Mn~(2+)及Fe(phen)_3~(2+),phen表示邻菲罗啉)的催化下,酸性溴酸盐氧化一些有机物时会发生化学振荡反应,而在某氧化过程中,有的中间物(如Br~-)的浓度,可出现2至3次极大值,振荡次数较少,被称为寡振荡反应。这类反应与生物钟现象类似,因此研究这类反应,尤其是氨基酸的寡振荡反应,可解释生命体内普遍存在的振荡现象。本文简要报道研究谷氨酸(以Gla表示)-KBrO_3-Mn~(2+)-Fe(phen)_3~(2+)-H_2SO_4体系的寡振荡反应的实验。
Under the catalysis of metal ions (common ce ~ (3 +), Mn ~ (2+) and Fe (phen) _3 ~ (2 +), phen stands for phenanthroline), acidic bromate oxidizes some organic compounds When a certain oxidation process, some intermediates (such as Br ~ -) concentration, there may be 2 to 3 times the maximum value, the number of oscillations less, known as the oligoclinic reaction. This kind of reaction is similar to the phenomenon of the biological clock. Therefore, the study of such reactions, especially the oligoclinic reaction of amino acids, can explain the oscillation phenomenon prevailing in the body of life. This article briefly reports the oligoclinic reaction of glutamic acid (represented by Gla) -KBrO_3-Mn ~ (2 +) - Fe (phen) _3 ~ (2 +) - H_2SO_4 system.
