국문 초록 (Abstract)

여러 혼합 용매 내에서Methyl 4-(Bromomethyl)Benzoate의 가용매 분해반응에 대한 반응 속도상수를 45.1℃에서 적정법을 이용하여 측정하였다. 얻어진 반응 속도 테이터를 이용하여 Grunwald-Winstein식에 적용하였다.GC분석법을 이용하여 반응 생성물들을 확인하고,그들의 상대적인 처센트를 결정하였다. 또한 Methyl 4-(Bromomethyl)Benzoate의 가용매 분해 반응에 대한활성화엔탈피와 활성화 엔트로피를 반응속도상수로부터 계산하였다. 이러한 실험 결과로부터 성화 엔탈피와 활성화 엔트로피를 반응속도상수로부터 계산하였다. 이러한 실험 결과로부터 Methyl 4-(Bromomethyl)Benzoate는 모든 용매 내에서 결합 형성이 우선하는 이분자 반응으로 추정됨을 알 수 있었다.

다국어 초록 (Multilingual Abstract)

The specific rates for the solvolyses of methyl 4-(bromomethyl)benzoate in a wide range of solvents have been measured by using the titrimetric method at 45.1℃. From the obtained kinetic data, the specific rates were applied to the Grunwald-Winstein equation using the values for N_T and Y_Br. In addition to the kinetic study, gas chromatography was used to identify the products as well as to determine their relative percentages. Also, the values of activation enthalpy and activation entropy for the solvolyses of methyl 4-(bromomethyl)benzoate were calculated from the rate constants measured at various temperatures. From those results, it could be estimated that the solvolysis of methyl 4-(bromoinethyl)benzoate proceeded through a bimolecular pathway which prefers a bond formation in all the solvents.
