초록

Nylon 66의 precursor인 Adiponitrile(ADN)의 전해합성에 대한 전극재료, 유화액 제조를 위한 계면활성제 그리고 반응물인 AN의 전기화학적 특성들을 조사하였다. 양극재료로는 내식성과 낮은 산소발생 과전압을 갖는 Dimensional Stable Anode(DSA)가 좋다. 분극특성으로부터 Electrohydrodimerization(EHD) 반응은 초기에는 -1.2∼-1.3V(vs. Hg/Hg₂Cl₂)에서 시작되나 시간이 경과함에 따라 양극과 음극 모두 전위의 변화가 일어나는 것으로 보아 실제로는 약 -7.8V(vs. Hg/Hg₂Cl₂)에서 ADN의 합성반응이 진행되는 것으로 생각된다. 계면활성제로 quaternary ammonium salts(QAS)는 대부분 적합하다.

Electrosynthesis of adiponitrile (ADN), a precursor for Nylon 66, was investigated by characterization of the effect of electrode materials, additives, and reactant AN. DSA was used as a anode material, which is well known to the corrosion resitive and has low oxygen overvoltage. Polarization characteristics show that the initial step of EHD reaction occurs at about -1.2∼-1.3V(vs Hg/Hg₂Cl₂), but the final ADN synthesis reaction appears to occur at about -7.8V( vs Hg/Hg₂C1₂) looking at the electrode potential change along time. The quaternary ammonium salts were acceptable for the electrosynthesis of ADN.
