Abstract
유기반응메카니즘과 압력과의 상관관계를 속도론적으로 연구하였다. 진공 및 고압장치를 이용하여 반응속도를 측정하여 다양한 활성화파라미터들을 계산하였으며, 다양한 압력과 온도에서 치환기변화에 따른 Hammett 값을 구하여 반응메카니즘의 변화를 연구하였다. 특히, 열역학함수들과 활성화부피와의 관계로부터 압력변화에 따라 전이상태 구조에 변화가 생김을 알 수 있었다.

Correlations of organic reaction mechanism with pressure have been studied by kinetics. Various activation parameters were calculated from reaction rate in vacuum and high pressure apparatuses. Besides the change of reaction mechanism were studied from the Hammett -values by changing pressure, temperature and substituent. The relation of thermodynamics with activation volume suggests that the transition state changes upon changing pressures.
