액체용액에서 활동도계수 모델의 열역학 및 통계역학적 고찰 = Thermodynamic and Statistical Mechanical Investigation of the Activity-Coefficient Models in Liquid Solutions

다국어 초록 (Multilingual Abstract)

Attempts are made to investigate the TPTT(two parameters two terms) equations to estimate the activity-coefficients of chemical solution from the solution thermodynamics and statistical mechanical theory.
As the effect of molecular interaction among molecules in the soultion is largely significant, it is found that the TPTT equations in general have difficulties to express various multicomponent systems due to their excessive simplification based on solution theory. It is found that the parameters of the TPTT equations are varying with the concentration of a solution based on statistical mechanical local composition theory.
This eventually leads us to seek a better method of estimating phase equilibria properties for non-ideal mixtures.
