摘要： 用循环伏安法研究中性载体ETH1117推动H+通过水/硝基苯界面的转移。通过络合使H+穿过水/硝基苯界面转移,是受扩散控制的可逆过程,ETH1117与H+在硝基苯相的配合比为1:1,配合物的稳定常数β0为2.9×107,扩散系数D为4.2×10-6cm2/s。

Abstract: Facilitated transfer of proton across the water/nitrobenzen interface was studied with cyclic voltammetry in the presence of N, N' -diheptyl-N, N' dimethylsuccinic acid diamide (ETH1117) in the nitrobenzene phase. The neutral carrier acts as the carrier, the complex formation makes the translocation of the ion across the water/nitrobenzene interface. The transfer of proton across the interface is a reversible process controlled by diffusion. The complex ratio of the complex of proton and ETH1117 in nitrobenzene is 1: 1 and the stability constant is 2.9× 107. The diffusion coefficient of ETH1117 in nitrobenzene is 4. 2×106cm/s.
