Abstract

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.
