298,15 K de Dörtlü Sıvı Karışımların Fazla Molar Hacimlerinin Tahmini

298.15 K'de üçlü n-hekzanol + etanitril + diklorometan ve dörtlü sistem n-hekzanol + etanitril + diklorometan + tetrahidrofuran için fazla molar hacimler simetrik ve asimetrik modeller kullanılarak hesaplanmıştır. Chou'nun Genel çözüm modeli, n-heksanol + etanitril + diklorometan + tetrahidrofuranda üçlü n-hekzanol + etanitril + diklorometan ve dörtlü sistemlerin fazla molar hacmini değerlendirmek için kullanılmıştır. Her iki karışım sistemi için deneysel veriler ve fazla molar hacimlerin hesaplanan sonuçları arasındaki iyi uyum, bu yaklaşımın çok bileşenli sistemlerin fazla molar hacimlerini tahmin etmek için başarıyla kullanılabileceğini gösterir.

Prediction of Excess Molar Volumes for Quaternary Liquid Mixtures at 298.15 K

The excess molar volumes for the ternary n-hexanol + ethanenitrile + dichloromethane and quaternary system n-hexanol + ethanenitrile + dichloromethane + tetrahydrofuran at 298.15K has been calculated by using symmetric and asymmetric models. Chou’s General solution model has been employed to evaluate the excess molar volume of the ternary n-hexanol + ethanenitrile + dichloromethane and quaternary systems in the n-hexanol + ethanenitrile + dichloromethane + tetrahydrofuran. The good agreement between experimental data and calculated results of excess molar volumes for both mixture systems indicates that this approach can be successfully used to predict the excess molar volumes of multicomponent systems.

Keywords:
