| Popis: | Molar volumes, excess molar volumes, and partial molar volumes were investigated for glycerol formal + ethanol mixtures by density measurements at several temperatures. Excess molar volumes are fitted by the Redlich-Kister equation and compared with other systems. The system exhibits negative excess volumes, probably due to increased H-bond interactions. Volume thermal expansion coefficients are also calculated. The Jouyban-Acree model was used for density and molar volume correlations at different temperatures. The mean relative deviations between experimental and calculated data were 0.03 ± 0.03% and 0.17 ± 0.13%, respectively, for density and molar volume data. Also, using a minimum number of data points, the Jouyban-Acree model can predict density and molar volume with acceptable accuracies (0.03 ± 0.03% and 0.15 ± 0.12%, respectively). |
