Abstract
여러가지 수용성 혼합용매와 에탄올-TFE 혼합용매에서 시안화 벤조일의 가용매분해반응에 대한 유사-1차반응속도상수를 1, 5, 10, 15, 20℃에서 구하였다. Kivinen polt의 n값, Grunwald-Winstein polt의 m값, Leffler 관계식의 β값, 확정된 Grunwald-Winstein식의 m 및 l값을 구하였다. More O'Ferrall polt와 양자역학적 해석 방법을 이용하여 용매 변화에 따른 전이상태 변화를 논의하였으며 본 반응은 associative SN2 반응 메카니즘으로 진행됨을 알 수 있었다.

The pseudo-first order rate constants have been obtained for the solvolysis of benzoyl cyanide in various aqueous solvent mixtures and ethanol-trifluoroethanol mixtures at 1, 5, 10, 15 and 20℃. Values of n in the Kivinen polt, m values of Grunwald-Winstein polt, β values of Leffler relationship and values of m and l in the extended Grunwald-Winstein polt have been calculated and studied the transition state variation caused by solvent changes using the More O'Ferrall polt and quantum mechanical approach. It has been shown that the reaction proceed via the associative SN2 mechanism, using the transition state parameters and quantum mechanical model approach.
