%X 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 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 ¡À 0.03% and 0.17 ¡À 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 ¡À 0.03% and 0.15 ¡À 0.12%, respectively).
