因为生命体内存在周期性振荡现象,因而药物对振荡反应的影响成为人们日益关注的问题。合成了一种药物中间体,并对其进行了元素分析、红外光谱、核磁共振表征,证明它是4-甲基-2,6-二羟基嘧啶。在不同温度和不同浓度下在B-Z振荡反应体系中加入4-甲基-2,6-二羟基嘧啶,考察其对B-Z振荡反应体系的影响。实验结果表明,温度升高使B-Z振荡反应体系的振荡周期减小。4-甲基-2,6-二羟基嘧啶浓度增大使B-Z振荡反应体系的振荡周期和振幅均产生减小现象。并对4-甲基-2,6-二羟基嘧啶的反应机理进行了推测。
Because of the existence of periodic oscillations in the body of the body, the influence of the drug on the oscillatory reaction has become a matter of increasing concern. A pharmaceutical intermediate was synthesized and characterized by elemental analysis, FTIR and 1H NMR. It was proved to be 4-methyl-2,6-dihydroxypyrimidine. At different temperatures and different concentrations, 4-methyl-2,6-dihydroxypyrimidine was added to the B-Z oscillation reaction system to investigate its effect on the B-Z oscillation reaction system. The experimental results show that the oscillation period of the B-Z oscillatory reaction system decreases with the increase of temperature. When the concentration of 4-methyl-2,6-dihydroxypyrimidine increases, the oscillation period and amplitude of the B-Z oscillating reaction system decrease. The reaction mechanism of 4-methyl-2,6-dihydroxypyrimidine was also presumed.
