The Effect of Pressure on the Rate of Solvolysis (Ⅲ) Kinetics on the Nucleophilic Substitution Reactions of Acyl- and Alkyl groups in Binary Solvents 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.

Abstract
|
|
|
|
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.
