Abstract
여러가지 수용성 혼합용매내에서 파라 치환체인 acylchloride류와 alkyl chloride류의 가용매분해 반응속도를 여러 온도와 압력하에서 전도도 방법에 의하여 측정하였다. 이들 속도상수로 부터 활성화 파라미터들(△V≠, 俎≠, △S≠)을 구하였다. 또한 활성화 부피와 활성화 엔트로피 관계로 부터 이들 반응에 대한 반응성을 조사하였다.

Kinetics for the solvolyses of acyl chlorides and alkyl chlorides in hydroxylic solvent mixtures have been measured by conductometric method at various temperatures and pressures. The activation parameters (ΔV≠, ΔH≠, ΔS≠) were estimated from the rate constants. The reactivities of these reactions were also estimated from the correlation of the activation volumes with the activation entropies.
