摘要
本文研究了酸度和温度对银配合物与联氨定向反应的影响,在不同的pH和温度下,微量Cu(Ⅱ)离子的加入均能有效地提高N_2H_4的四电子定向反应率;N_2H_4的四电子反应率随体系pH和温度的提高呈有序增加,无Cu(Ⅱ)离子存在时,N_2H_4的四电子反应率与银配合物的logβ_2呈线性关系。Cu(Ⅱ)离子存在时,N_2H_4单电子反应率的对数与1/logβ_2呈线性关系。
On the basis of our previous work, the directional reaction of hydrazine with several silver coordination compounds has been studied at different acidity and temperature. We found that if a trsce amount of copper(Ⅱ) ion is present in the reaction system,the fourelcotron direetional reaction of hydrazine is greatly increased under different pH or temperature conditions.The ratio of four-electron directional reaction of hydrazine is orderly increased with the inereasing of pH value or temperature.The ratio of foureleetron reaction against logβ_2 of several silver coordination compounds is linear in the absence of copper(Ⅱ) ion.In the presence of copper(Ⅱ)ion, the logarithm of the ratio of one-electron reaction of hydrazine is proportional to 1/logβ_2.
