Comparison of Experimental Data on the Fluctuation Integral G_ij with the Calculated Results Based on the Activity Coefficient Model in Binary Mixtures Containing c-Hexane

c-hexane을 포함하는 이성분계 혼합물에서 활동도계수 모델을 이용한 변동적분 G_ij의 계산 수치와 실험 수치의 비교

The fluctuation integrals which give useful information in the structure of solution are associated with the mixed direct correlation integral ($C_{12}$) known. Using its weighted arithmetic mean of $C_{11}$ and $C_{22}$ and the activity coefficient model, the fluctuation integrals on solute-solute, solvent-solute, and solvent-solvent can be calculated in the function of mole fraction. In this work, several binary mixtures containing c-hexane were tested and the results on the fluctuation integrals were rather good.
