Abstract
Ethanol-water mixture 내에서 일어나는 p-nitrobenzyl chloride의 solvolysis반응에 대한 열역학적 parameter를 구하고 이 data를 δMΔH≠ = a'Y + bδMΔS≠에 적용함으로써 반응상수 a'가 50% 이하의 alcohol solvent에서나 50% 이상의 alcohol solvent에서 같다는 것을 알 수 있었다. 즉 water-rich solvent에서나 alcohol-rich solvent에서나 solvolysis반응의 mechanism은 변함이 없다는 것을 알았다.

The thermodynamic parameters for the solvolysis of the p-nitrobenzyl chloride which take place in the ethanol-water mixture media were determined. From the application of this data to the formula δMΔH≠ = a'Y + bδMΔS≠ the following conclusion was obtained. The substrate constant a' for this reaction was not varied in the media which contain more than 50% alcohol and less than 50% alcohol. From this, it is clear that the mechanism of this reaction is the same both in the water-rich solvent and in the alcohol-rich solvent.
