Zusammenfassung:The polarographic behavior of 1-(2-pyridylazo)-2-naphthol (PAN) in acetonitrile as an aprotic solvent has been investigated. The reduction of PAN in $10^{-2}$ molarity of tetraethyl-ammonium perchlorate acetonitrile solution proceeds along two one-electron steps to give the corresponding hydrazo compound. Every reduction wave was diffusion controlled and considerably reversible. The reduction mechanism of PAN in acetonitrile is estimated as follows; 반양성자성 용매인 아세토니트릴 중에서 1-(2-pyridylazo)-2-naphthol (PAN)의 폴라로그래프법적 거동을 조사하였다. $10^{-2}$몰농도의 과염소산 테트라에틸암모늄 아세토니트릴 용액에서 PAN은 1전자 2단계의 환원과정을 거쳐 hydrazo화합물이 되었다. 각 환원파는 확산지배적이었고 가역성도 비교적 좋았다. 아세토니트릴에서 PAN의 환원반응 메카니즘은 아래와 같이 결론지을 수 있다.
